7 interviews, started with a phone screen, then a conference call interview, a second phone interview as I passed each one higher level management fielded the interviews. I was then brought in for a screen interview and testing to verify my skill set, this included what appeared to be a IQ test and personality test. Then I had a series of 3 interviews with what I would later learn was lead manaagementon multiple teams.
Offer was sent in 48 hours from final interview. I was told prior to the final 3 that those would be my last interviews.
