I applied through an employee referral. I interviewed at Gartner (San Diego, CA) in Dec 2016
Interview
3, 30 minute phone interviews with current consultants, more of a conversational nature and inquiries as to why you would want to work at Gartner Consulting.
After, a take home case study is provided that you have 1 week to work on, during that time you also are connected to HR who confirm some details and paperwork.
Your in office interview is 4 hours, and you sit down with 3 senior consultants/directors, and then present your case study results to a room full of consultants who proceed to ask you questions and attempt to poke holes in your conclusions.

The process involved 4 rounds: 1. HR basic detail clarification round, 2. Technical round if interview with hiring manager, 3. Case study, 4. Interview with a panel of 2-3 Senior Directors to check your fit with the firm.

Question 1
My research and analytical capabilities across multiple sources to create a triangulated solution to a given problem.
Interview experience was terrible. Interviewer arrived two hours late, wasted my time, and only revealed at the end that the role didn’t even exist. Completely unprofessional and frustrating for candidates.
Lengthy multiple phase interview which included a typical job interview followed by a business case.
The questions were mostly personal with a strong focus on fit and feeling out how much of a grinder you are.
The business case was quite hard (it was on the education sector, weird) and I had to develop a single slide solution a very short space of time on a very rubbish laptop.
All in all - the whole process seemed design to fail people not pass them.
