I recently applied for an internal vacancy after some issues working with my current team. The position will help me basically double my tech stack in size, the team seems to have much better dynamics and the position is a step more senior from my current which will save me at least a couple years in trajectory easily. I have been told I have the position and pretty much waiting on the paperwork after the holiday week.
What worries me is that this happened very quickly and during a time with very high tensions between me and line management. I looked into internal vacancies and found this position on a Friday (10 mins after this conversation), the informal interview was over the weekend which I aced and the formal interview was within a week with a thumbs up.
The new team within this big multinational company also just happens to be in the same area my current team is already seated, which will make for some awkward times.
I am already accepting this will burn some bridges with the soon-to-be-old team but I am worried the sudden lateral promotion after a couple of heated incidents, located at the exact same site and seating will cause some drama or even draw some retaliation.
What are some things I can do to make the switch as smooth as possible and avoid the drama?
