I applied through university. The process took 4 weeks. I interviewed at Gartner (Los Angeles, CA) in Aug 2017
Interview
Applied through my university career center.
First round is an on-campus interview with 2 senior/director level consultants. 30-mins each. Asked you the general behavioral questions, why Gartner, a couple Fermi estimation questions.
Second round is an invitation to their offices to interview with 3 managing partners (MP) for 1-hr each. You then have a 30-min case study presentation in front of 6-10 consultants & MPs who will question your logic, numbers, and thought process. Meant to simulate a real client.
They give you the case study 1 week before the interview. This was exceptionally tough for those who are working full-time and also attending night classes. Very thorough researched need to be done.
The whole process was exceptionally smooth. Consultants were professional and friendly. Recruiter was responsive and helpful.

Question 1
Fermi estimation questions - i.e. how many golf balls fit into a Boeing 747, etc.
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.
Interview questions [1]
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.
