It was an on campus interview, so it won’t dig into too much about your research or experience. The interview focusing no whether you have enough background knowledge. Also, at the end of the interview they will allow some time for you to ask them questions

I had 2 rounds of interview for this position. The 1st round was with the Hiring Manager. The interview lasted for around 45 minutes - 1 hour. The interview's questions revolved around project experience, knowledge check, and personality-related question. I received the 2nd round of interview 1 month after the 1st round. I did this interview with the Manager from different team but inside the same department as this position. The interview lasted for around 30-45 minutes and it is mainly personality-related questions. The experience with the HR for this position was quite bad as there was no constant communication between the candidate and the HR.
