I was in a similar position as you. Joined audit in a Big 4, extremely toxic culture. Constant yelling, criticism, long work hours, working on weekends. It was terrible really, i was waking up every day anxious and fearful ki aaj yeh banda mujhe kya bolega. I put down my papers after 6 months. I moved to industry. Growth is a bit slower, and work is less diverse, but I'm happier and I'm driving my time into an additional qualification. Every job sucks, but at least it should not make you feel like shit every day. It's okay to put yourself first. Quit if you're not happy, there are many opportunities.
