The first call was just to let me know that the application had been accepted and a recruiter would call me for the first round of the interview.

1st Round - Asked me aptitude questions like how I tackled a difficult situation in the past, if I had worked in a team and what problems I faced, how I overcame those problems. And many more STAR questions. Any negative feedback given to me in the past, how I handled it. What I think is my best trait, etc., etc.

2nd Round - With Technical Recruiter. He discussed the whole resume with me. No technical questions, but he asked me what kind of projects and technologies I had worked on. He was trying to judge which team would be the best match for me to continue to the final round.

3rd Round - With Team Leaders. Two leaders were on the call. One had a technical background and the other had a BA background.

Asked basic object-oriented questions and a lot of project-specific questions. Discussed my resume and asked me what my goals are. What I think is the best role for me. How comfortable I am in switching technologies.

Tell me one time when you worked in a team and had to face problems, and how you fixed it.

Have you ever worked with a difficult lead, and how did you handle that situation?

Have you ever made a mistake at work, and how did you handle that situation?

Basic OOP questions.

Have you ever received negative feedback, and what did you do about it?
