Cognizant interview questions

It's an easy interview. All are basic questions on Java, sql, DBMS, OOPS. Questions on projects and random hr questions etc. Interviewer was so Friendly. He comforted throughout the interview. It's an virtual interview.

In the third interview, with the product managment team, I was asked mostly technical architecture and business questions, in my opinion, inproper of a designer interview. Luckily, before designing, I've developed software for many years and have a lot of knowledge. So I could answer with full confidence. Worse still is that the interviewer confused himself on some of the technical questions and ended up confusing me. I had to correct him at a given point, and that meant I was out. It was a question about PWAs that, just by chance, I had worked on a month ago.
