First interview was a phone screen, which covered the basics of object oriented design. Second interview came a couple months later and was on site with three individual engineers. This interview was bit more in debt, it involved 3 questions related to algorithm design, application design and a high level implementation the database objects required to store the applications data with the correct normalization. The questions were quite manageable and came from regular scenarios which would occur in most enterprise solutions. The last interview was over the phone and was strategically focused on the technologies that position required. Mostly focus on SOA and the Microsoft stack which can be used to build these type of solutions.
