Got the interview from a campus recruiting event. Shortly after, I interviewed on campus for about 20 minutes. About a week later, I received an email regarding a second interview. It was a 3 day interviewing process. First night is intros, presentations (you have to make a short group presentation with the group youre assigned), and some ice breakers. This goes on until about 2 am. The next morning you head to a rig and do a tour of that then you come back to the hotel and do exit interviews followed by a group dinner.

1st round interview included short technical question, and telling about myself and the projects I worked on. Not difficult/or hard, but just need to explain well enough to tell the logic process
