Are there a lot of python backend teams at FB/Meta?

Hello, I recently got a fb new grad offer and I am strongly considering it; a big pro for working at fb for me would be that I can work on python backend teams since I enjoy working in python. I know that there is a bootcamp process in which you get to choose your team, and I wanted to know if it was guaranteed to be able to find a team that works in python backend. I know Instagram works in python but I want to know how much they hire and if its almost guaranteed to be able to find a team that is hiring new grads over there. Wanted to get some insight before accepting since this is pretty important to me. Also would these teams have decent WLB compared to the rest of fb, how would it vary compared to the rest of the company since I assume these would most likely be product teams? For context, I will be in NYC #software #swe #facebook #meta #instagram #nyc #newgrad
