Three interviews: first behavioral with manager, two subsequent interviews both technical. First one solve programming problems, second technical find bug in a program by the computer. Overall very common computer software and science type questions. For the technical interviews I met two of the best people I have ever work with. Very knowledge and nice in sharing knowledge both during interview and even after I started work in there. I really miss working and learning from the people at Sophos. I wish I had started work there earlier in my career.
