1 screening call, 1 video call with Hiring Manager, 2 Video Calls with Panel and Business. Generally polite interviewers, final call with business pretty cold, quick and straight forward, mostly business oriented. During the whole process several late time changes on appointed meeting (even 15 minutes before the arranged time), name of panel interviewers were constantly changing, so people I was expecting to meet during the interviews weren't present due to not clear reasons.
