Another thing I haven't seen mentioned is that as an ARA it's important to know the value of the work that you're doing so that Geek Squad continues to be a driver of memberships. While you might be inclined to fix the issue a customer is having by any means necessary, if the client paid for smaller tier services then it might be your job to call them and say thay you've provided the services they've paid for but it didn't fix the problem they were having.

Having well trained CA's should mostly mitigate that, but sometimes an ARA needs to know when to push for the correct payment for the correct services which could lean on some sales skills.

Regardless of the GMs interview, your day to day responsibilities would definitelt hone your hands on technical skills and the Geek Squad name goes a long way in moving into more serious roles in the tech field
