Contacted by a 3rd party recruiter. Had initial screen with an internal recruiter, which went well. Over the next several weeks, interviewed with 3 people in middle and upper management on the tech side. Finally met with a panel of people I would be managing.
After that, I was completely ghosted. Reached out to the internal recruiter multiple times with no reply. The 3rd party recruiter was surprised and disappointed, but wasn't able to get a response either. Poor etiquette after a long interview process.
