The sequence of interviews was as follows: Applied on Linkedin; short call with HR; call with hiring manager; Gallup interview; call with hiring director; flown out to Amsterdam RHQ for one on ones and small panel interviews; followup call with HR; salary negotiations; finally received offer. Took a few months as the European team took their time between interviews and also answering all my questions. A little bit different from the typical American, Fortune 500 company interview and hiring schedule (even though the company is based in USA)
