DevOps interviews: talk through the incident

DevOps rounds lean on scenarios: a failed deploy, a full disk, a slow pipeline. Mockinto lets you rehearse explaining them calmly, using the tools on your own résumé.

An example question

“A deploy went out and error rates doubled. What do you do in the first ten minutes?”

Interviewers want to hear priorities: protect users first (roll back or switch off), then investigate, then communicate.

Example written by the Mockinto team. Your interview’s questions are written for your résumé or job description.

What you will practise

Topics that come up for devops engineers

Questions follow the skills in your résumé or the job description, so these are typical areas rather than a fixed script.

01 CI/CD pipelines and release strategies
02 Containers and orchestration, such as Docker and Kubernetes
03 Cloud services on your résumé, such as AWS, Azure or GCP
04 Monitoring, alerting and incident response
05 Infrastructure as code
06 Working with developers under pressure

How to prepare with Mockinto

Rehearse, read the report, rehearse again

How a session works

Upload your résumé as a PDF or paste the job description. Mockinto writes about 30 questions for that role, a mix of HR, experience, aptitude and technical questions, and you answer each one out loud. When you finish, you get a report with an overall score out of 100, a score for each skill and feedback on every answer.

Rehearse scenarios

Scenario questions are easier when you have said a structure aloud before: what you check, what you change, how you confirm it worked.

Cloud roles too

Cloud engineer interviews overlap heavily with DevOps. Paste a cloud job description and the questions follow it.

What you get back

A report on every answer

Sample report · illustrative data, not a real candidate

Overall score

68 out of 100

Role: Backend developer, fresher
Questions: 30
Built from: A sample résumé (Java, Spring Boot, MySQL)

Skill scores

Java and Spring Boot 74/100
Databases and SQL 61/100
API design 70/100

Summary. Clear on core Java and REST basics. Answers on databases stayed general: name the index or the query plan you would check. HR answers were honest but long; lead with the result. One question was skipped and scored zero.

Q1 HR Tell me about yourself. 7/10

Your answer (transcript)

“I am a final-year computer science student. I built a library management system in Spring Boot for my college, and I interned for two months at a small fintech where I wrote REST endpoints…”

What went well

Opens with who you are and two concrete projects. The internship gives the interviewer something to ask about.

What could be better

At nearly three minutes it runs long. End with one line on why this role, and cut the list of college clubs.

A model answer

I am a final-year computer science student who builds backend services. At college I built a library system in Spring Boot and MySQL, and at my internship I wrote REST endpoints for a fintech app. I want a junior backend role where I can ship APIs and learn how production systems run.

Q7 Technical How would you speed up a slow query that filters orders by customer and date? 5/10

Your answer (transcript)

“I would first check if there is an index. If not, I would add an index on the customer column. I would also try to fetch fewer columns…”

What went well

Checks indexing first, which is the right instinct, and mentions selecting fewer columns.

What could be better

Say how you would confirm the cause, for example with EXPLAIN, and consider one composite index on customer and date rather than a single column.

A model answer

I would start with EXPLAIN to see whether the query scans the whole table. If it does, I would add a composite index on customer and order date, in that order, so the filter and the sort can both use it. I would select only the columns I need, then run EXPLAIN again to confirm the plan changed.

This is a sample built by the Mockinto team from illustrative data to show the report format. It is not a real candidate’s result, and the answers are written for the example.

Does this cover cloud engineer interviews?

Yes. Paste a cloud engineer job description, or use a résumé that lists your cloud work, and the questions follow it.

Are there hands-on labs?

No. Mockinto is a spoken interview with a scored report. It does not provide servers or labs.

Can I practise on my phone?

The Android and iOS apps are not public yet. Until they are, you can practise in the web app. Mockinto works in a current version of a modern browser on desktop or phone.
