I applied online at career site and got first a technical phone interview and then onsite. It was 4 hours long interview with 5 different people in 5 separate sessions. It was professional, but a bit lengthy and 2 of interviewer's sessions were unnecessary. First session was dedicated to explain company's product which was very helpful and informative. The Recruiter who received or setup interview were always in a bit rush never sit and dropped email after two days that i was not selected. She asked herself that she would provide me a feedback next day but never replied back to my emails that was very unprofessional.
