I applied through a recruiter. The process took 3 months. I interviewed at Gartner (Arlington, VA) in May 2009
Interview
I was contacted by a recruiter who asked a few basic questions about my business development experience, then sent me a timed personality test. I think it was about 30 mins long. A couple of days later she contacted me to say I was a good fit for the company and we set the interview date for about a month later.
The interview itself was casual with run of the mill questions about sales prowess, why Gartner, previous work experience challenges and my expectations of the position I was interviewing for.
