I don’t think moving between regionals is bad, it’s being stagnant at the regionals is bad. picking up side duties like EQ Coord, training in classroom or on the floor, ASAP, heck even working OTand keeping your head down and working being a valuable and reliable member of the team is most important.
Don’t be the one that is popping up on the radar, or always away his/her desk. Lastly, always keep learning. Spend a week learn the centers, next week the states, next week start going over city codes, charts, etc. I did that and it all started to click and helped in the interview.
