Overall a positive experience of the process. Disappointed to not receive an offer considering the amount of preparation that needs to be done in order to be successful (or not, in my case).
3 stage process:
1st stage: Informal call with a Recruiter - research Gartner, why sales and try to be charismatic and you'll get through this one.
2nd stage: Formal call with a different Recruiter - STAR questions e.g. Tell me about a time when you were challenged by a leader. Tell me about a time you faced rejection etc. etc. This was fairly tough - I'd recommend doing a lot of preparation on scenarios for the STAR questions. Again, identify why Sales & why Gartner.
3rd stage: Meeting with Hiring Manager(s). Overall another tough interview. Similar to the 2nd stage. Comprised of an introduction, STAR questions and a short roleplay which you will receive information on ahead of time.
Overall, it was really useful to receive feedback at each stage of the interview. Unfortunately, not a whole lot more I can offer in terms of preparation. It's largely to do with how you are on the day.
