They were all very nice during the phone screening and interview day - they showed us around the building, had lunch for us, and drinks during the break period. The interview consisted of 3 45-minute behavioral interview questions plus a case study and analytical assessment. I wouldn't say their interview process was difficult, it was just a little draining. The interview started at 8am and we wrapped up around 4pm. I felt pretty confident leaving but I think they were looking for someone with more experience. It was a little disheartening speaking them a few weeks following my interview. The positive experience I had interviewing was negated by the follow up email and phone calls that were not warm and friendly.
