Recruiter called me on a Saturday (I wasn't actively looking at the time). It was a very fast track interview process with multiple phone interviews with Directors, Principals and Partners on Sunday. Had only one face-to-face interview with another Senior Manager in a non-office setting on Monday. Then had a few more phone interviews on Monday and into Tuesday. By Wednesday, I was given a verbal offer. And within two days of that, I had the offer letter. All in all, it was less than a week from start to finish.
