Super easy, hired as a contractor before being as a full time employee. Regular onboarding: tons of paperwork, background checks.
Took about a week to get all details ironed out before being thrown into the deep end. Peers more than willing to help out with the getting up to speed.
The process took 2 days. I interviewed at RTX in Jan 2019
Interview
After telephonic interview, was called for personal interview which is a event for two days. Security verification & security clearance help followed by meeting with cold well bankers and relocation agency.
company benefits explanation followed by factory visit. On first day evening there is a reception & networking session during which, the candidate will meet hiring manager to secure more interviews for the next day.
Typically every candidate will get min one interview and maximum 4-5 interviews.
