The entire process consisted of four interviews (two sets of two back-to-back interviews). The first two took place on my college campus, and for the second two I was flown out to my preferred office. I got the interviews through networking emails and phone calls. All of my interviewers were very relaxed, though it was clear that they expected me to produce when it came to the case. Very brief small talk at the beginning - "What's your story?" kind of questions, and then they would jump into the case.
