I went through 2 rounds with many people. It was simple and not stressful. One was online interview and the other was in person interview. It was straight to the point.
It was held with different people, basically who ever could do the interview along with the supervisor and manager. The end was with Human Resources, it was pretty laid back
Smooth and very efficient. The recruiter was awesome as well. The interview itself felt like a conversation instead of an actual interview. I would highly recommend applying and exploring the opportunities they offer.
