UBS Software Engineer interview questions

Had a Phone Screen Interview first. Basic programming questions Then was invited to their office in Stamford for a 1:1 interview. Met with 3 developers in the group. All were completely technical interviews. There were designing questions, programming questions, general logic questions. Questions ranged from designing a class for implementation of ChessBoard game to writing code for some Linked List problem implementation. They focussed a lot on multithreading questions and discussed my experience with that. There was a question about string reversal as well which I had to code. Each interviewer spend 1/2 hr.
