Generally I see the people who took up the programming challenges belonging to these groups; Problem Solver. These are the group of people that all startups are looking to hire. In a way they love the programming challenge and want to prove themselves. They could potential rock the startup! Sometimes a bigger ego comes as a package for these talented individuals, be prepare to nurse. Job Seeker. They just want to get job, since you mentioned it. They will google, hack, etc.. anything to get it out so they can secure an interview. If they are to do it on the spot, not sure how many can really pass it again. Much work is required to filter them to find the one. Personally, I feel if they have some form of problem solving approach, like rare diamonds they can be processed further. Ideally a few good Problem Solvers mentoring and supported by a few learning Job Seeker delivered the best results for startups. I have never operate a successful startup before, dun take my word for it. :)
