First a phone interview and then an in-person interview at the HQ with a recruiter and several HR managers in a panel. Especially the interview with the recruiter seemed rushed as if I was a burden in her daily schedule. The panel interview was very zoomed in on experiences I had 4 years ago and had nothing to do with recent experiences. Questions I had were quickly brushed off and answered very superficially. Not a great experience.
( they also mentioned that the interview process for full-time positions can take up to 7 rounds in several months!!)
