Top Devops Interview Questions

Possible questions in the IT and IT interview

A systematic catalog of questions for the various IT professions

In this article, we will introduce you to general questions that may arise in job interviews in the IT industry, as well as questions that may arise in specific job interviews.

The purpose of an interview

The purpose of an interview is to find out more about the applicant than can be seen on paper. The boss would like to get a precise picture of you and learn things that go beyond your professional successes.

Information technology encompasses a wide range of different departments and work areas. In general, an interview will check whether you really know your way around information technology and to what extent your motivation for this field of work shows.

The goals of an interview:
  • Check competencies
  • Analyze personality
  • Check handling of pressure situations
  • Test your fit with the team
  • Overcoming excitement: knowing possible questions

    Almost everyone is a little excited before an interview. After all, everything should go well. Comprehensive preparation for the interview is essential for this. That doesn't just mean that you know your Mertier and yourself informed in detail about the company should have!

    A job interview in the IT industry is usually quite subject-specific. The questions therefore mostly relate to the position for which you have applied. Nevertheless, IT professionals can expect some standardized questions in the interview that do not explicitly relate to the job.

    The most common general questions in an IT interview

    There are a few standard questions that can appear in any interview. We encourage you to know exactly how you would answer these questions. If you are enthusiastic about IT and know where you want to go, the answers shouldn't be too difficult for you.

    • Do you have a manager who serves as a role model for you?

    • How do you stay up to date in IT?

    • How do you deal with stress in your job?

    • What developments do you see in the next 10 years?

    • In your opinion, how can a network be maintained both internally and externally?

    • "Which IT projects have you worked on in the past?" With this question, the HR manager can quickly find out in which areas you have already gained experience.

    • "What stage of development do you see yourself at?" This question plays a particularly important role in an interview for an apprenticeship position. In this way, the HR manager can see how much training is necessary. But even as a die-hard IT professional, you can face this question. After all, professional experience does not always mean that the applicant was actually able to develop further during these years.

    • "What is the current level of your programming skills?" Another important question in the interview for the apprenticeship position. The benefits for the HR manager are similar to those of the previous question.

    • "What would you improve on this source code?" A question for which the HR manager would like to hear a practical solution from you. In this way, he can check whether your details in the résumé were correct.

    • "What are the least things you can handle in your work environment?" With this question, the HR manager wants to find out whether you fit into the team as a person.

    • "What would induce you to stay with your previous company?" This question is a popular, alternative formulation to the question of why you want to leave your previous employer. The HR manager would like to find out what would have been particularly important to you. With this feedback, he can then better assess whether the potential new job can also meet your requirements.

    • "What is your experience with the XY technology?" This is where things get a little more precise and the HR manager may want to find out whether you have already been able to work with technologies that play an important role in your potential new job.

    • "You are good at using technology XY, as I have just seen on your résumé. Could you please explain to me exactly how you were able to apply this knowledge in your previous job?" With this question, it is very easy for the HR manager to find out whether the information on your CV is actually correct. If you state extensive knowledge in a certain area, you should of course be able to substantiate this with concrete examples and projects from your everyday work.

    • "What is the most interesting project you have worked on so far?" The HR manager asks this question to find out what motivates you. On the basis of this knowledge, it is then very easy to determine whether your motivation also fits the advertised position.

    • "Tell me about a failure that you experienced in your last job". Of course, this is not a question, but your answer plays an important role for the HR manager. At least he knows that mistakes are made in IT. It is important, however, that the culprit - in this case you - is able to admit his failure or mistake and to learn from it.

    2. "Why should you work in our company?" Here the HR manager doesn't just want to check your professional skills. He also wants to know how well you can sell yourself and how confident you are of yourself.

    3. "Why do you want to work in our company?" This question must not be confused with question number 2. Here the HR manager would like to know what your motivation is to introduce you to this company. So explain why you think the company is a good place to work for you.

    1. "How do you deal with conflicts?" As a business intelligence analyst, you will not be able to avoid communicating with others. This can lead to conflicts. In the interview, it makes sense if you explain how you would resolve conflicts. For example through targeted and individual discussions.

    2. "How was the culture at your previous work place?" With this question, the HR manager works off two important aspects. On the one hand, he learns what tasks you had in your previous job. On the other hand, with this question he also asks your knowledge of English.

    5. "Are you also ready to look after a customer on site for several days?" This question is extremely important. After all, not every customer is satisfied with the fact that the business intelligence analyst works from his branch. Some would like to have a competent person on site for the period of the analysis. If you are not ready, the company can adjust to it.

    The most common questions when interviewing a DevOps engineer

    The DevOps interview is primarily about your interdisciplinary skills. Therefore you have to expect the following questions.

    2. "Which DevOps tools do you already know?" Be sure to be honest here. There's no point in telling the HR manager about a tool you've only heard of before. Of course, it is important that you know at least the basic tools. The tools the company uses itself ultimately depends heavily on the size of the company.

    3. "What systems have you worked with so far?" Here the HR manager learns even more about your experiences and can get an idea of ​​your competencies. Of course, you should be familiar with the network hardware and architectures used to support workload distribution. In addition, extensive knowledge of servers and IT systems is of course an advantage.

    4. "What other tools do you know of that can help you with DevOps processes?" Especially if the company relies on standardized approaches in software development, you can score points with additional knowledge in the field of technology and tools for agile lifecycle management.

    5. "What is typical project management like for you?" Here you can bring in your experiences that you know and have already solved in connection with problems in DevOps project management. The HR manager finds out how good and clear your understanding of management techniques is.

    The most common questions when interviewing a data scientist

    As a data scientist, you mainly work with the data of a company. In the interview, however, you will also have to answer questions about yourself - regardless of your professional skills.

    1. "Which programming languages ​​do you speak?" An essential question that the HR manager asks. After all, you will have to process the collected data accordingly. Knowledge of the most important programming languages ​​is therefore mandatory.

    2. "What would make you stay with your old employer?" Just don't start here by telling how unfair and incompetent your last employer was. The previous employer should never be talked badly in the interview. Answer this question soberly and objectively. So the HR manager also knows what to do to make you enjoy working in his company.

    3. "Tell me about a mistake you made in your last job." Errors are human and do occur in IT. The HR manager is also aware of this. Therefore, report on a mistake that you actually made, but were subsequently able to resolve.

    4. "In your opinion, what five qualities should a data scientist have?" With this question you can score with your knowledge. Therefore, name particularly important characteristics that you too can demonstrate.

    5. "What is your salary expectation?" Give a confident answer to this question. Don't sell yourself below value and still stick to a reasonable number.

    1. "What are the phases of the STLC?" Your theoretical knowledge will be queried here. It is important that you know the phases of the software tester's life cycle.

    2. "Explain the bug lifecycle in detail." Strictly speaking, this is not a question, but your answer still plays an important role. Here you should be able to explain in a few concise sentences that the bug "lifecycle" goes through the stage of errors / defects before it is rejected, postponed or fixed.

    3. "What is meant by sanity tests adhoc test and smoke test?" Another subject-specific question that should help the HR manager to determine your professional competencies.

    4. "What is the difference between testing and debugging?" Based on your answer, the HR manager can now find out what your knowledge is.

    5. "Where do you see yourself in the next five years?" Now it's also about your personal attitude. The HR manager wants to find out what your motivations are and what goals you have. However, it is essential for the HR manager to find out whether you would like to stay as a tester in the respective company in the long term.

    The most common questions when interviewing a system engineer

    As a system engineer, you are aware of the entirety of a project. Your field of activity is diverse, which is why the questions in the interview can be very varied.

    1. "What experiences have you already gained?" Here the HR manager wants to find out more about your background. Now it can make sense if you put your certifications on the table and explain what competencies you have. Perhaps you can also explain some points from your résumé in more detail.

    2. "How well do you know about operating systems?" A subject-specific question that you should definitely be able to answer comprehensively. It is important that you have experience. However, hardly any HR manager will assume that you are familiar with all the services that will also play a role in your potential new position.

    3. "What was the hardest problem that you have ever solved?" Your task will be, among other things, to identify and solve problems in hardware and software. For the HR manager it is therefore interesting which problems you have already faced and what your solution is.

    4. "How do you monitor system performance?" This is a particularly subject-specific question. The HR manager simply wants to determine how good your theoretical and practical skills are.

    5. "How do you behave in support for endpoint systems?" As a system engineer, you will not only sit in front of your desk, but also possibly come into contact with customers. Your answer to this question tells the HR manager a lot about how you deal with users and which tools you would use to implement fast and comprehensive support.

    The most common interview questions for a frontend developer

    As a front-end developer, you are responsible for developing the presentation of a website. This is an important task that is only entrusted to the most competent person in a company.

    2. "What version management have you used so far?" With this question, the HR manager can find out more about your previous experience.

    3. "What is your workflow when developing a website?" With this question, the HR manager would like to determine whether you are familiar with current practice. In this way you can also find out how well you fit into the company and its processes.

    4. "Why does it make sense to intercept resources across more than one domain?" A short question that only needs a short answer.

    5. "How do you use XML in HTML?" As a frontend developer you will work a lot with HTML. Your wealth of knowledge in this area should therefore be correspondingly comprehensive.

    The most common interview questions for a penetration tester

    As a pen tester, you try to actively circumvent a company's existing security settings. In this way you can show how vulnerable a system, operating system or web application is. Of course, companies want to hire particularly competent testers who are also able to uncover hidden gaps.

    1. "Explain which programming languages ​​you speak." As a penetration tester you should of course have knowledge of the languages ​​C, Java, Python and PHP. Otherwise the job is almost impossible.

    2. "Which tools are you familiar with and which ones do you particularly enjoy working with?" Here the HR manager would like to find out how extensive your knowledge is. At the same time, your answer also tells them which tools you are particularly familiar with and to what extent their company can benefit from them.

    3. "Are you ready to get help when you need it?" As a penetration tester, you will always face small challenges. It is not always easy to cope with these. With this question, the HR manager would like to find out at what point you accept help - whether too early or too late or at exactly the right time.

    4. "What attack techniques are you familiar with?" As a competent penetration tester you should of course be up to date and know all attack techniques that would also be used by outsiders. This is the only way you can ensure more security in the systems.

    5. "How would you document your approach?" As a penetration tester, you are of course obliged to meticulously document all processes. With this question, the HR manager would like to find out whether you are also capable of this.

    The most common interview questions for (system) administrators

    (System) administrators install, configure and maintain the software and hardware within the group IT. Administrators often work together with other IT people. Not only specialist knowledge and practical skills, but also a certain ability to work in a team are required.

    1. "What is your technical background?" With this question, the HR manager would like to find out the formal requirements under which you were trained. As a rule, solid basics in the field of computer science are required here. In some cases, however, the recruiter also wants to see entry-level certifications or certifications that are related to a very specific technology. You may not have such a certification. Sometimes that's not that bad, then you can score with other, similar experiences. By the way, it makes sense if, when describing your training and your certifications, you also emphasize how much they helped you back then and what great advantage each individual investment brought with it.

    2. "How do you deal with support for users and endpoint systems?" As a (system) administrator, you will often not only have to deal with the data center, but also with the end users and their equipment. It is now important that you sufficiently explain to the HR manager how familiar you are with remote desktop administration or with help desk ticket systems. Maybe you can name some of the tools in a very specific way and explain how well you are used to them.

    3. "How do you handle backups and restores in your current workplace?" With this question, the HR manager wants to find out how familiar you are with certain backup tools. On the basis of your answer, he will also be able to deduce how good your understanding of the practical principles in these areas is. Here you can explain how to verify and test backups so that they can be restored later.

    4. "What was the trickiest problem you ever solved?" As a (system) administrator, you are of course an expert when it comes to troubleshooting and detecting and solving hardware problems. The HR manager would like to know exactly. Therefore, use a suitable and up-to-date example to explain how you identify a problem, how you use system logs to find out the cause, how you test the performance with common tools and what other measures you have taken to find a solution. In this way, you show your counterpart that you are able to act sensibly, use diagnostic tools effectively and address problems so that functionality is quickly restored. By the way, it makes sense if you also emphasize which services and applications you used during the process.

    5. "What KPIs would you use to monitor system performance?" As a (system) administrator, it is of course your job to monitor the performance and availability of the systems. The HR manager asks the above question in order to be able to estimate to what extent you are able to maintain the hardware, plan backups, evaluate important event logs and solve problems.

    The most common job interview questions for IT specialists for system integration

    As an IT specialist for system integration, you are wanted in larger companies as well as in independent software and system houses. Since your area of ​​work can be very different, the questions in the interview can also vary greatly.

    1. "What advantages do you see with Java over C ++?" Here the HR manager would like to find out how well you are familiar with the subject. At the same time, through your answer, he also learns something about your previous training and can thus get a better picture of your current level of knowledge.

    2. "What are the biggest IT trends for you at the moment?" With this question, the HR manager would like to find out whether you are not only familiar with the theory, but also know about current topics.

    3. "Why do you think you are the perfect fit for the job?" Be sure to forego too much modesty here. The HR manager would like to know why you in particular qualify for the job as an IT specialist for system integration and provide the company with a high level of benefit. Why? Because there may be a lot of applicants in this profession and you should stand out from your competition in some way.

    4. "How would you explain topic XY to a non-IT expert?" With this question, the HR manager can quickly find out whether you are also suitable for contact with customers. It is not for nothing that they hire an IT specialist to check and maintain their systems. Nevertheless, if there is a problem, your client naturally wants to know what the reason is. You should be able to explain this briefly, precisely and, above all, understandably.

    5. "You have the choice: either you complete a project on time and incompletely, or completely and late. What do you choose?" At first glance, this question seems tricky. The answer, however, is that you sit down with your project manager and your team and you work together to find a solution. This makes it clear what this question is aimed at: the HR manager wants to find out whether you are able to admit your own mistakes (even in front of the team) and still try to find a solution.

    The most common interview questions for IT specialists

    As an IT specialist, too, you often face strong competition in the application process. It is therefore also important here that you are prepared for the most frequently asked questions.

    1. "What can you tell me about programming details for ...?" With this question, the HR manager would like to test your specialist knowledge. As a rule, of course, you are asked about programming that also plays an important role in the company. A short, concise answer can be just as correct here as a detailed answer.

    2. "Tell us about one of your projects". This question is usually not primarily about the project itself. The HR manager will possibly follow up on some points and ask you about your behavior in certain situations. In this way he can get to know you and your way of working better, recognize at which points you might need help and whether you are actually making use of the help you need.

    3. "Where do you see yourself in the next ten years?" A standard question that is particularly popular with IT specialists. After all, they are often still at the beginning of their careers. The HR manager wants to find out how ambitious you are, but also whether you want to stay with the company for the long term.

    4. "What role does money play for you?" Now of course you could answer with "Money doesn't matter to me" or "Money is totally unimportant to me". However, you shouldn't do that if possible. With this question, the HR manager tests how self-confident you are - after all, you don't just go to work for fun. Explain that you believe that good work should be rewarded accordingly.

    5. "Which programming languages ​​do you speak?" This question is probably self-explanatory. It is important for the company to know which programming languages ​​you have a perfect command of. This is the only way the HR manager can find out whether you are suitable for the position. However, always be honest here, false information could quickly take revenge.

    The most common interview questions for first, second and third level supporters

    First, second and third level support is almost standard in large companies. However, since these specialists are also in contact with the customer, great importance is attached to knowledge during the job interview.

    1. "Can you tell me something about your hobbies?" This question is meant rather sporadically. What the HR manager actually wants to know is how good your English skills are. These are simply essential for a first, second or third level supporter.

    2. "How difficult do you find it to receive help?" As a first and second level supporter, you of course have to know when to switch to the next higher level. Quick problem solving is the be-all and end-all here - an employee who is too proud and does not want to seek help would be out of place here.

    3. "What salary do you have?" An important question that is self-explanatory. It is important that you give a self-confident answer and that your desired salary is not set too low. At the same time, however, it should of course not go beyond all framework, but rather be appropriate.

    4. "The person you are talking to is a difficult and excited customer. How do you behave?" Social competence is an important quality in this professional field. Every day you will deal with people who want a satisfactory answer to their problem in the shortest possible time. It is important that you can keep calm and always remain professional despite unfriendly comments.

    5. "What do you think are the most important tasks in your new job?" Based on your answer to this question, the HR manager can determine whether your expectations are realistic. If this is not the case, it can slow down your euphoria so that you are not disappointed later.

    The most common interview questions for IT product managers

    You will design marketing and sales strategies for products, product groups or services. It is of course important to your employer that you can actually do this and ultimately help the company to be successful.

    1. "Which steps do you think are particularly important when planning a launch readiness?" Here the HR manager can immediately determine how high your skills are and whether you are a good fit for the company.

    2. "Which developments are particularly topical in our industry?" With this question it is very easy to find out whether you have already dealt with the industry of your potential new employer in advance.

    3. "What measures were you able to take yourself when launching a product?" With this question, the HR manager would like to know how much experience you have already gained, whether you know your way around and whether your measures also fit the company and the product.

    4. "What five qualities would a new IT product manager need to bring to your team?" Be extra careful here. Now you have to combine your strengths with the requirements of the job. In this way you can explain to the HR manager why you are so suitable for the job.

    5. "What would your support for an account manager look like?" This question is primarily aimed at your ability to work in a team. Do you know what your support could look like? If so, that's great. If not, the HR manager now knows that you have not shown any teamwork so far - at least in this respect. Avoid answering "I don't know" at all costs.

    The most common interview questions for an IT consultant
