I was contacted by a recruiter via LinkedIn and completed two technical phone interviews, each lasting 45 minutes.

Both interviewers were not entirely personable nor interactive, and I was generally unimpressed by the nature of my interviews.

My recruiter was especially helpful, however, and the process was professional and clear. The entire process took around 4 weeks from initial recruitment to rejection.

I moved past the first technical interview and was then rejected after the second call.

Given a list of People, find the Celebrity. Assume a celebrity is defined as a person that:

a) Is followed by every single person in the list. b) Follows nobody in the list.
