Meta Engineer interview questions

I was contacted by an employee through LinkedIn, who performed a phone screening before setting me up with a member of their technical team for a technical phone interview. I passed the technical interview and they invited me to interview on site. The interviews were 100% technical and the answers were very challenging.

Watch out, this company flies you out and takes care of the hotel, but they don't mention ground transportation, and you get stuck with a pretty hefty bill if you don't know your way around. As for the interview, they send a lot of mixed messages - the website states that you should dress business for the interview, but I was dissed by one of the staff for doing exactly that (I was overdressed!). In general, I found a lack of mature, objective questions and comments from some of the interview team, who were more interested if I fit in than whether I could do the job. It felt like I was back in high school and I was expected to be cool enough to be allowed into the "A" group. The pay and benefits are good, and I'm sure it's a good place to work if you're good at being part of the "A" group. I think this company needs some maturity and consistency.
