Good luck on the new job.
I avoided large organizations for 25 years, except for stints as an independent contractor. Finally had to join megacorp, and it has been an interesting 5 years. I've had 5 different managers, which is somewhat unusual, and have one great lesson to pass on. If it all possible, pick a manager, not a job.
My 5th manager (for 1.5 years) has made a great difference in how I feel about the job. Also, I may meet with him once or twice a month, but email and text on a regular basis. I really understand how to do work, and don't need micro-managing. I also don't need the pressure which accompanies a 10-25% downsizing, and the boss realizes that. So he shares background information. Knowing about possible growth opportunities keeps me sane.
It sounds like your new boss will have many of the same qualities as mine.
