I had a skype/webex first round interview with the vendor. I was asked questions in Java and related frameworks for 30 mins and was given a problem and was asked to solve.
After I cleared the first interview, I had phone/webex interview conducted by Architect and Team lead. I was given two problems to solve, one in java and one in java script. To me, it looked like in addition to me solving/answering the questions with explanation, the interviewers were looking if I was asking the right questions related to the problems.
