I'm preparing for an AWS Technical Account Manager interview loop and haven't been able to get clear answers from recruiting about the technical interviews. During the phone screen, I was told that the Technical Depth interview would focus on two specific domains, but the loop invitation didn't identify them. How are those domains chosen, and how advanced do the questions usually get? Should I expect troubleshooting scenarios in addition to conceptual questions? I'm also curious whether the Technical Breadth interview is similar to the phone screen, with fundamentals across many areas, and whether troubleshooting is included there as well.

Breadth is generally broader and more fundamentals-oriented. You may move across several AWS domains and be asked to explain how the services work, when you’d use them, and how you’d approach common problems. The more deeply you can explain the areas you claim experience with, the better.
The depth interview usually focuses on about two technical domains and goes reasonably deep, including troubleshooting. The exact areas may depend on what you indicated in your technical self-assessment or questionnaire, so be ready to explain your experience beyond the fundamentals. Networking, compute, storage, and RDS are all sensible areas to review.
In many interview loops, the domains are selected from the competency areas listed on the candidate questionnaire. If you marked yourself as proficient in a subject, interviewers may probe that area in detail, so it’s worth refreshing every domain you identified rather than preparing only one or two.
