I interviewed there several years ago and although the interview process was long (several phone interviews and then a full day on-sight) it never really felt like a hard interview process. Of course after I interviewed there I heard nothing from them for 2 months, assumed they weren't interested, then they gave me a written offer out of the blue for a completely different job that had nothing to do with what I'd interviewed for and wasn't really aligned with my skills or interests, so I have no idea what kind of bizzaro twilight zone interview process I might have fallen into.
