Had an initial phone screen with HR and later had a technical phone interview the hiring manager. I had 4 technical rounds and one non-technical -- 2 engineers, 2 managers and a director; though I had a chance to grill the managers and director about the culture, the team and the company in more general. HR contacted me a few days later to tell me they were going to extend an offer; but wanted to know my salary range but I declined and politely asked that they make an offer -- only to come back few days later saying they were moving on to another candidate. I figured it came down to compensation considering where I was coming from -- but that was just unprofessional on their part. Got a solid offer few weeks later at a brand name company -- even better.
