Meta Sr. Software Engineer interview questions

First of all, a recruiter emailed me to schedule a 30 minutes call with him. In this round will be asked just simple questions about your career and explain all the process steps you should follow to receive an offer. The next round was two medium-difficulty algorithms.

This is a multiple level process, the first being just a screening phone call and the second one being a 45-minute coding interview. This part is pretty challenging as you have to resolve one or two challenges without the possibility to compile.
