Accept offer one week ago but very regret
I was pushed to accept one MM IB offer one week ago. This whole week I keep regret to accept it. I don't have any other offer yet, but I think I should keep looking instead of accepting. I don't have any otherbut has some random , private equity, private fund group in BB/IB.
If I send MM shop and say I don't want go their place any more, what will happen? There are so many horror story about reneging. I am very scared if they mad at me and ruin my career. Should I talk to school career service center about this situation. Can I withdrew my acceptance? It is for next year 2023 SA. I think they have more than 1 year to find new person.
Any suggestion is appreciated! I keep worrying and regretting this all the time after accepting.
