I just took part in the first round on-campus interview, and my interviewer is a partner from tax department. He is not very talkative, only asked me 2-3 simple questions.
I applied through college or university. I interviewed at PwC
Interview
One 30 minute on campus interview. Got extended to the second round. Now in the middle of preparation for the next interview. Before the on-campus interview, there is a pre-reception event to network with the recruiter and client service representatives. It's very relaxing environment. It's a good chance to ask questions and get to know the people in the company. The on campus interview is all behavioral type of questions.
