Interview process: strong, informative and efficient! I was explained the full process until hire so I knew exactly what to expect. My two contacts within the recruitment department were absolutely wonderful. They showed great patience and really want you to succeed to reach to the offer stage.
They do extra when you are in doubt and have you speak to team members and managers.
Phone interviews: 2 or 3 depending
Video call or on site: 1
Panel interview: Final
Advice: Preparation is key
Understand the company thoroughly
Showcase your quick thinking sales experience on the spot
I chose at the time not to continue because of personal reasons but hope in the future to work for Gartner.
