It is a bit of a longer process. I was approached by a recruiter if you went the same route as myself.
You'll met with the Manager of the department , then you have individual meetings with each of the Senior TAMs. All the while they will be asking you about yourself to see if your are a good fit along side some technical questions to see where your knowledge of the industry is.
Where it will get difficult and agitating is there is a single point of failure which is your recruiter and scheduling. Your recruiter is the one point which can tank your entire interview process.
You have to be EXTREMELY diligent with the time slots you choose otherwise they will just select anytime, and even if you do choose specific slots they might still choose anytime outside of that. You will have to specify which Time Zone you are in and clarify that they are putting you in the correct time zone. If you miss meetings due to these failures they will place that on you so make sure to keep your emails saved and screenshot.
Outside of that the TAM team seems really great fun and on their Ps&Qs.
