Bad experience. Had a screening round over call too with HR and CTO. They kept on increasing the interview rounds on the spot. 1. They called for an aptitude and a technical F2F round, but they added a written technical round. Gave no response that day. After 2 weeks, they called again and scheduled another technical round. (It was supposed to be a final discussion but added another round) 2. The interviewers were always late and had to wait for hours.
