I would never interview or even collaborate with the people in this team or recommend working with the people in this group. Manager was completely unprofessional and harpy. I was interviewed by people who were not even involved with the team and were unaware of why they were asked to interview me. I was interviewed by 5 people for 5 hours in succession. The manager and principal engineer who were initially forcing me to interview did not even have the courtesy to get back. I have a feeling their so called new project did not get funded.

They go over your resume first. If they like you, they want you apply online if you have not done that then they call you for a phone screening. After phone screening, if you pass, they invite you for a f2f interview. You need to prepare for that and make yourself available for an entire day. If everything works well, they may interview you more or submit an offer.
