It was a good interview process, with initial hr round, pair programming, and technical round. There were no tricky ds/algo questions. Mostly about the OOP design skill, and other technical design choices.

Asked one of the employee for referral. 1. Got a call from HR asking about the project, technology and contribution and she convivence to schedule interview with one the Thought worker. This discussion happened for 20mins 2. First round of virtual F2F: Some java github code has been shared with me and asked to do analysis on interview I asked to make some enhancement in the project and write test cases. I cleared it. Duration 90 mins but end up 120mins. 3. Second Round: Develop a game from scratch as console application and make sure write test case. This is the easiest one for me only two or three use cases where asked. 4. Third Round: Tech discussion about project and technology. Asked about my project architecture. Since I'm a full stack developer I did contributed to my project a lot. So went to explain everything I know at the end I was asked to design class and relation for OLA/UBER booking. I managed to give my design using SOLID principle which they expected in all round of interview. No negative comment where shared during the discussion. Two days after I got a call from HR saying that I went to answer everything which I'm not aware of. I'm disappointment after receiving such comment. It takes me for a while to move on from such comment after begin honest during the entire process but I'm assume communication gap was there in the last round.
