First round was based on python coding, file handling, django concepts, HLD, etc. Be hands on with deep pythonic coding and system design principles. Better to have medium AWS knowledge like S3, EC2, ECS, RDS. Caching using Redis or similar technology.

I didn't appear for there interview, I just got a call from the HR and their criteria for appearing for the interview is apparently very high. I have almost 6 years of experience and I have worked with both product and service based companies, and my clients in service based companies have been product based, but they said they only need employees from product based companies and this is so lame, how can you judge anything or any candidate before the interview and even when I am working in a product based setup. No clue what this was.
