It was a one day event inclusive of a logical reasoning test and 3 rounds of interview. The first round was more informal with the section manager, the second with the department manager and the last with director. The interviewers were generally friendly and the first two rounds focuses more on your resume. The director interview might have bigger questions such as your career aspiration etc.

It lasted for an hour and asked questions about self-introduction, work experience, and problem-solving experience. In particular, I asked deeply about the process experience. Also, interviewers require expertise and creativity.
