There were 3 rounds of interview. This was back in 2017. All rounds were good. They were friendly at the same time professional setting the expectations from you,at the same time giving a hearty welcome to the company. I still remember the one thing all three interviewers said to me was that dont change yourself. We hired you for all the things you add to this work such as passion,enthusiasm about work etc. Do not change that. Learn all the professionalism but dont let go of the passion and enthusiasm. This is something which has remained with me even today.
