Not extensive but in detail. There were two interviews but the first one was just with the talent recruiter. I was not referred but worked as a client at TCS for Boeing
I applied online. The process took 5 weeks. I interviewed at Boeing (Seattle, WA) in Mar 2020
Interview
Thorough, I had to go through multiple rounds of interviews. I would interview again. The hiring manager seemed difficult to please, at least, that was my impression. The people interviewing changed with each round, it dis not seem consistent.
You want to use STAR format responses. The interview is not very long maybe 3-4 questions and a few follow up questions. Use the format for all questions to get some brownie points.
