Jumpshot interview questions

I've got coding homework, I could choose any language for that. Then I was interviewed by HR manager, that was easy and then challenged by two senior QAs. They were asking quite a lot questions, also asking details of that homework.

I did three interviews, with the cursory HR call being the first, and everybody with whom I spoke seemed intelligent and nice enough. Needing a job, I feigned being impressed with their offering, but there was a lot of “spin” about what they were offering up that told me that something smelled.
