How are interdisciplinary degrees viewed by disciplinary (AACSB) faculty hiring committees?
When a department looks to hire, they have to make an official statement about which degrees should apply to the position. So the first place to look is job ads for positions you are interested in. There should be a sentence like, "Applicants should have a Ph.D. in ..." to show the "acceptable" degrees. As Business schools typically hire in the Fall, there should be many examples of these job ads currently circulating.

However, what departments do is more important than what they say. Notably, departments may say they are open to interdisciplinary degrees, but then only hire from disciplinary programs. To check this, you should look at the CVs of current faculty at AACSB schools who have HR focus and see what their qualifications are. Especially look at newer faculty hires. If some substantial portion of current faculty come from interdisciplinary degrees like the one you are considering, then I think you would be in good shape. Otherwise, I would reconsider your plan.
