I applied through a recruiter. The process took 2 weeks. I interviewed at Gartner (Fort Myers, FL) in Oct 2017
Interview
They described the process as follows: initial engagement, phone screen with recruiter, deeper phone screen with senior recruiter, phone interview with manager, field day in FL office.
This company is cult-like. They only hire you if you live, breathe, and eat Gartner. I asked what their decision making criteria would be and the recruiter's response was "personality". Personality is important, but they should value background and history as well. If you do not LOVE working as a team, going to outings with your co-workers, and essentially sacrificing your social life for Gartner - then this won't be a good fit for you. I'm guessing the culture here is based on favoritism. I do not want to work in a place like that.
They have reached out to me for a job every year and I have interviewed with them 2 times and have never made it past the 1st interview. Confused why a recruiter reaches out to me anymore?
It was long and rigorous, often feeling extremely high pressure, with not a lot of constructive criticism. There are 5 rounds and each with a role-play. It's safe to say this is not an easy interview process. I'm not sure how they do their prospecting, but I was apparently a 'great fit' for the role - didn't show that enthusiasm during our calls.
Intensive - multiple rounds led by a recruiter. Expect 2 rounds of role play, around 4 rounds total. 2 with a recruiter, one with a lead skills expert and another panel with VPs and hiring managers.
