Meta Software Developer interview questions

They called me on Bluejeans, didn't work well, so they called me on the phone, the sound wasn't good either. The guy on the other side of the phone had a very thick accent, quite hard to understand. He told me to skip the introductory part because we couldn't hear each other well.

Applied online in their career website, emailed recruiter (I previously applied for internship position at Facebook too). No coding challenge. Got invited for a technical phone interview round -- using a code editor and video call, rejected after the technical interview round. The next round after the phone interview should be onsite interviews.
