Meta Developer interview questions

Submitted my resume/cover letter to Facebook to apply for a software engineering internship. I heard back from a recruiter in a couple of weeks, asking about my availability to set up a phone interview. I responded with my available dates, and never heard from the recruiter again. I sent one or two more follow-up emails, and still never heard back from the recruiter after the first email. Very professional, Facebook.

I applied on facebook/careers and was contact by their HR for a screening test which consists of some behavioral questions and a few simple questions about c/c++ & Algo, such as what's a virtual destructor. And then they scheduled me for a tech phone interview during which I was asked to do two programming questions on Collabedit.com.
