Maria's availability for Strategic Reviews varies widely based on time of year and what we've got going on internally at ApplicantLab.
If she has availability for Strategic Reviews you will see it on the booking pages!
Given the amount of time she'd dedicating to answering the support inbox, in recent years she's only had time to do HBS mock interviews.
However, please rest assured that our team is very experienced -- you're in good hands! Plus, if you have follow-up questions after your service with someone else, you can first ask your reviewer to clarify, and then beyond that you can reach out to Maria for clarifications via the support inbox, if needed!
