1st have 2 phone interviews, each asked several technique questions and talked about my resume
Then it had a on-site interview. In a meeting room, 5 persons came to the meeting room one by one. and the overall interview lasted 3+ hours including a meal.
I cant expose exact question because of the contract. All I can say is for coding part it was just some very easy and common string coding problems. Also some general questions for my resume were asked.
