The first round was your usual Data Structures. They asked to solve in a TDD way, and it was a pair programming round. The round was conducted smoothly.

I had a very bad experience in the second round. I was asked to come at 9:00 AM on a weekday, but the round only started at 10:30 AM after the interviewer arrived. I was made to wait for the entire time. The round was very technology-specific. I was asked to work on an ongoing project using Python with a particular framework (this violates the very idea of microservices). I was again asked about my experience and for an introduction. Clearly, the interviewer hadn't gone through my CV. I had high expectations from the company, but they seem to be looking for specific technologies, like a service company.

I would only consider this company if you are desperate.

Custom implementation of a Set.
