For instance, you may manage a team of engineers you used to be close to, and they might not be as transparent or friendly now that you became their manager. On the other hand, if you use to share your worries and challenges with your colleagues as a contributor, it’s unlikely you will keep sharing with the same people after making the transition, because they are your reports now, or maybe because only managers could relate to those problems. All those points aren’t to stop you from becoming an Engineering Manager, but they can be insightful to manage your expectations.
