Very conversational and I thought it went well. I did not move onto the next round however. I think it largely depends on what school you attend. I moved all the way onto the last round but my Interviewer was great.

Structured. It consist of 3 rounds in total. HR will host the interview. First round of Case Study, then Technical with the team leads of the team. After that, will be Q&A session. Lastly with the head of the department.
