Feeling really nervous about promo bc I work with mostly L4s; probably won't go for it until march or next sept. Any uplifting stories or advice people care to share?
no promo committee any more for L4, isn't it
Go for it. The worst that could happen is that you get feedback on how to improve for next cycle.
Is it true that you guys can put in a promotion request by yourself? Can one's management chain influence the decision?
you can but you should let your manager know
L3 to L4 should be pretty easy. Go for it early and don't get discouraged if you are rejected. Just try again next cycle.
