They sent an email 2 days before the interview. They wan not fully prepared (In the begging the security guy did not allow me to enter and the email contains a number which is for another country). When I went inside an FSE and Operation manager was inside and they met me inside an office.

was very professional, and the interview was with the product line manager and HR personnel as well. they ask about my major and why you want to work with a service company etc
