Meta Software Engineer interview questions

I applied to Facebook through their website and got a call from the recruiter the next day. He asked the standard screening questions and set up a technical phone screen for later that week. The phone screen was done using coderpad.io, and they threw me off from the very beginning by setting up a C++ environment although I had told the recruiter that I was most comfortable in Python and although I never claimed anywhere that I had any familiarity with C++. Still, interview questions tend to be general enough that, as long as you aren't completely unfamiliar with the language syntax, you can generally do a decent job in any language. So off we went in C++. The interviewer was very pleasant, and even gave me some tips for how to improve my resume at the beginning. Then we dived into the coding. He had actually chosen a great question to determine my programming ability. Unfortunately, I botched it by making too many assumptions about the question and not considering carefully enough what lay behind the interface that the interviewer had provided me. This all happened maybe two or three weeks ago and I am sure that I won't be progressing to the next step. The one negative in all this is that the recruiter has not followed up at all with me. Yes, rejection is not uncommon when applying at a company like Facebook, but that doesn't mean that the company shouldn't have the courtesy to at least inform you of it. So overall, great experience in the beginning but I was turned off by the lack of respect for the process that I sensed from the recruiter.

Interview was for software engineer. I got the interview call through career fair at campus. It was a telephonic interview for 45 min. The interviewer was very polite and helpful. In the end I messed up things. It started off with the interviewer introducing himself, and asked to introduce my self. Then some behavioral questions, like why Facebook, which team, either Front-end or Back-end are you interested in, and a couple of questions on my projects and resume. The interviewed happened on a Thursday. At the end of the interview, the interviewer told "Sorry! Time's-up". Then itself I understood, I would not clear it. Next monday, I got a mail from the recruiter, that they can't move forward.
