I guess in those cases, you just have to learn to recognize the "Microsoft way". I luckily haven't had to. I came close to working with one of their ERPs (I believe they have or have had multiple), but the company ended up reorganizing and didn't hire anyone that round. Went to work with Odoo instead, which is an open source competitor, sorta (in both cases I'm talking about custom module developments at a consultancy; I don't work for Odoo itself and was never gonna work for M$). Now there's a nonzero chance I might start my own consultancy sometime in a year or 2, in which case I'll have to take the Odoo certification test and find 2 employees (friends at first most likely) to do the same, one of the criteria for silver level partnership which gets more visibility.
