There was and 4 round interview. 1) Tecnical round three interviews was there for frontend, backend and full stack developers. 2) Practical round, I got an full stack practical crating api and integration on frontend. 3) Manager round, management level questions related client communication and diff case in client handling. 4) HR round.

After you answered their question and if it was wrong they laughed. You can hear that in the call. So as per personal experience no professionalism at all during the interview process.
