Call with recruiter 2 round of technical interview. Complex data structures, threading and related question. Discussion on previous experience. I found the interviewers quite friendly. Asked me to how to code a problem. No needed even write the code. Pseudo-code or even just explaining verbally is good enough.

The first round was a 30 minute screening interview. The interviewer was busy and seemed to be in a hurry. It was a rapid fire session of Java questions. He seemed disinterested in conducting the interview and was just asking question after question.
