Recently a colleague told me that the project she is working is going to end and that she must choose another team/project to work next, so she is trying to understand where she might fit better (both from the technical and management style).
She is considering working in a project within the department I work for. This department has several teams and a few managers. As I have worked several years in this department with virtually all managers (direct report and others), I know how they work.
I did not have time to provide any meaningful piece of the advice yet, but from my perspective (both first hand experience and confirmed by many other colleagues) there are only two managers that I would recommend to work for in this department.
Of course, it is easy to recommend these managers and provide an explanation, but what about the others? There are many reasons I can use to explain why not them, but this is badmouthing and this is a no-no.
Question: How to convey to a coworker the explanation for avoiding working for some managers without badmouthing them?
