Getting dragged around (AE Promotion)

Close to being in the SDR position for a little over a year now at this firm.

Originally started training for different parts of the AE role in Jan. I've been trained on all segments of the typical AE deal cycle including mutual evaluation plans, procurement, security, NDAs, and pricing. I've also run multiple first calls or discovery calls leading to prospects taking the next steps. I've also done sales training in my free time (course/bootcamp).

Have been told since the start of the summer that I am on track and should be promoted in the coming weeks or months (I have been leading performance or second in performance and SQOs throughout these quarters). Leaders' only concern at that time was my participation during sales-wide meetings and that I should be offering advice more.

Recently received feedback regarding quarterly performance saying that I need to be more assertive about my career aspirations and skillset. Citing the participation, lack of mentorship to others (I've mentored SDRs), and a lack of agenda or challenges to work on for 1:1 meetings.

However, I have been coming to 1:1s with common topics to hit on and I have mentored SDRs. My participation in team meetings is lacking but when most meetings are AE-focused, I don't have much to offer.

Now has been mentioned recently that this needs to be worked on for the coming months to ensure an AE position. Says that I am ready to make it happen!

This is extremely frustrating to me. I've asked AEs for advice and have been told to lead the 1:1 meetings more as if it were a discovery or sales call. I've also talked about holding training sessions. In my spare time, I have been volunteering for tutoring to help build leadership skills too.

What am I doing wrong?
