- When did you get introduced to DevOps? The recruiter couldn't define what DevOps was for him, the question wasn't about just tools (which is good), but it felt that DevOps as a principle of automating everything and providing infrastructure to development teams wasn't the expected answer.
- There was a question about data processing pipelines. My understanding that it was about using SQL vs NoSQL databases for storing data, but I could be wrong.
- The question about preferable authentication and authorization mechanism for a bunch of services interacting with each other. During that question, I think, the interviewer mentioned OAuth. I have a feeling that my answer about JWT tokens was not satisfactory. But OAuth is not great for services interacting with each other, it is more for a user to grant some service access to own data in another service, but the interviewer didn't mention such user-service interactions.
