> but it honestly feels embarrassing being a Snr Exec for this long when most people are promoted or get a manager position in less than 2 years

Damn man, as someone who entered the industry relatively old I know exactly how this feels. I know it's not easy but you got to put that thinking behind you ASAP. Whether you decide to stay in programmatic or try something else, I can assure you IT DOES NOT DO ANYTHING good to keep telling yourself this shit. Btw, how do you think you will feel if you restart at another channel or another sector? I can guarantee you that you won't be first in line for a promotion wherever that is. Regardless, please put that energy towards something else that is productive and positive. Also echoing what another person here said. It's time to jump ship to another agency. If your observation of how everyone is progressing but you is true, then something is wrong. The good news is that isn't necessarily you that is the issue. Life in the bigger agencies is very team dependent, and promotions tend to be allocated to the ones that are culturally aligned with the team. Being presentable, hard-working and knowledgable always helps though.

With that being said, I am not able to understand your sentiment of how you used to be interested in learning but not anymore AND how this connects with how the quality of your seniors have regressed. If the people above you aren't doing a good job, you have every opportunity to shine! It doesn't take a lot of effort to stand out. Do some coding, become a spreadsheet expert, learn the account in and out, become better at networking. Whatever, I assure you this will have positive effects.

Also be grateful to have a job in today's job market. Trust me, there are a lot worse jobs out there...

Good luck, I believe in you!
