Whether get promoted or not, run away if not seeing a clear career path. Also, don’t feel guilty to leave right after promotion. You earned it.
What do u mean by a clear career path ? Does it mean spoon feeding of projects by the manager ? Can u pls explain ?
Learning, growing and gaining reputations.
Stay in the same job after a promo only if you see yourself having the opportunity to grow further or that you love the job so much you don't care. Else change.
