This position was a finance student assistant position. One or two weeks after applying, I was told to do the PLI/PI tests. I thought I had done really poorly, but to my surprise a few weeks later I was called by HR to come in for an interview.
The first thing that happened was I was required to retake the PLI test in the office.
Afterwards, there were two interviews, one was conducted by a HR representative and it had many typical HR questions about strengths, weaknesses, how I have faced difficult situations, how I react under stress. Then she talked about my results in the PLI and PI tests and she seemed pleased with them.
Then came the interview with the two hiring managers, a lot of questions followed about me, and I was unable to answer a question (What do you think you would do at this job?). Thus, my advice is to really look into the job offer and what you would be doing, even though it's not clear from the job description, try to guess what it would be about, because otherwise you won't be able to close.
At the end, you will have the chance to ask your own questions, and I asked what I would be doing at the job, since I was unable to answer, and then gave me a detailed description about it. I was not offered the job.
