RedHat was the worst when it came to this. In 2007, I interviewed for a professional services position within RedHat. I had a phone screen and then three or four weeks would go by, and then the recruiter would ask me for another phone screen. It eventually ended up with a stay in Chicago for an in-person...series of phone calls and one face-to-face interview. Another six months(!) went by before they called me to ask me if I would be interested in working with them and started the verbal negotiation process. Suffice to say, I turned them down (my work situation had changed and I wasn't looking to leave), but, I always remember that process and the length of time that it took to get there when I hear friends talking about applying to RedHat.
