Met up with 5 other potential candidates in Milpitas and had lunch with interviewers while listening to a KLA-Tencor introduction presentation. We were then split up to have individual 30 minute interviews with the Apps development hiring team. They asked basic team-based scenario questions and some estimation questions to see how well we can think on our feet. One of the interviewers tested us to see if we could come up with methods to determine if there are defects in a picture, assuming we are given the original picture as a basis.
