I interviewed through my school at a university recruiting event. I met with two people, the recruiter and a senior consultant. They were very friendly and asked me many practical questions; tell me about yourself, your goals, etc. They also asked me how I would approach the task of finding out how many traffic lights were in the city of Philadelphia. I thought this was an odd question, but I guess they wanted to see my thought process and whether I can think outside the box. Worst part of the recruiting experience was being told that I was a good fit for the role, but never hearing from them again. Extremely unprofessional.
