Meta Machine Learning Engineer interview questions

Recruiter reached out to me via email and set up an initial coding interview and provided a lot of helpful resources for it. An online tool was used for coding while on video call with recruiter

I was contacted by a recruiter on linkedin who scheduled a call with a recruiter from their Machine Learning team. The recruiter I talked to was one of the worst recruiters I've ever come across in bay area (though it is quite possible she is actually working out of their Bangalore office). She was rude, uncultured, uncouth and frankly I am surprised that such a rude individual works for Facebook. She was extremely arrogant and I still don't know what she was so arrogant about. I guess she is arrogant of the fact that she works at Facebook? So what? First, you are a recruiter without any tech skills. Second, there are many other hot startups which are pre-ipo and will be more lucrative than working for whatever pathetic team that hired you. After talking to her I did not even want to pursue this job anymore. If this is the kind of people that work at FB, I don't want to work there. FB culture used to be good. What happened?!!
