UR & DS are combined, which is nice in some ways but they expect Product Insights managers to have deep knowledge of both disciplines in order to advance in their career. This just doesn't work for DS, it's not at all a skill that's likely to be useful in a next career step.
Also many Directors got to where they are merely by being on the team for a long time, not by being super strong managers. In the mean-time a lot of formal hurdles and extra requirements have been put up, so it can be hard to get a promotion nowadays which can be really frustrating if you are a more recent hire.
