Gartner hires based on traits. Competitive, sense of purpose, motivated... You'll speak to a couple of recruiters that will identify what role you might be best suited for. After they identify you would be good fit for the AE role you move on to a manager interview. Typically two managers. After which you could be required to write a follow up email with what you learned so far in the hiring process, the company, etc... After this there is a panel interview in which you will present about YOU. WHY YOU. WHY You now format. And you will also do a role play. It helps if you have an internal reference to submit your resume.

Got in touch by a recruiter and came across very professional. Asked me good questions, however challenged me on my location and unfortunately I was required to be in the office every single day which was 1hr and 30mins drive which was certainly not ideal. I was impressed with their approach and trying to find the right people for the right job.
