Meta Sr. Software Engineer interview questions

It was 5 rounds with one recruiter call then I had to talk to engineers from two different teams that all did Leetcode style interviews. Finally I had an onsite with people from 3 different organizations and ultimately they made an offer. I had to go through team matching after the on site.

Hard they kept asking me to do dfs and hard algorithms as part fontwhnrocoeas and it was a pain and difficult you know if you look at blind or reddit for info
