Call/phone screen with HR, set up a meeting with the head of engineering at the facility, VP of facility, and one of the senior engineers. 5 hour long interview. Took them twice as long as they anticipated to get back to me. I couldn't get anyone to let me know what was going on, so I figured I'd been ghosted. Moved on and am happily employed elsewhere.

Got a call screening from HR Manager who set an interview on the phone with the hiring manager. Second interview in loco with hiring manager and after third interview with company management got a offer.
