PopCap Games Software Engineer-II interview questions

Questions about algorithms (array manipulation, object-oriented patterns) and a question about architecture were the bulk of the on-site questions. The array-oriented algorithm question was done as part of the pair programming portion, and I found this to be the only part of the interview that was unsatisfactory. I was paired with an individual who appeared to be intentionally obstructing me by refusing to answer questions and saying "just do whatever you want", and would flat out tell me I was wrong about certain algorithmic aspects that I was actually correct about (which I attribute to their lack of familiarity with the language that we were using, in spite of that language being the language that I was being hired to write in).
