High attrition, toxic culture, weird incentives

Working at a Paytm subsidiary. My manager left the firm 6 months ago and instead of hiring a replacement I was given all his work with no increment or bonus.

I worked my ass off and ensured there were no issues. Come appraisal time, no promotion, 5% increment, lot of bonus esops with (5%, 5%, 10%, 10%, 70%) vesting. This is the most weird vesting period I've come across and almost looks they are trying to trap me into staying here.

My experience is not unique. A lot of senior people left last year and they haven't hired but rather dumped their work on juniors.

I feel like an idiot for trusting the firm to reward my work.
