My edited comment didn’t save, but I wanted to add that I realize social psychology PhD students also get jobs in business schools. I have been told OB programs are typically (somewhat) less competitive for admission (especially with my interests in emotions and intergroup relations, which are common interests in social psychology and less common for business applicants, considering my strong research fit for faculty in both fields) and that many programs collaborate heavily with the psychology departments. After working for 5 years as an HR manager the interdisciplinary focus is important to me, regardless of whether job prospects are any better in the business world - but it’s always good to know what I am getting myself into.
