Meta Software Developer interview questions

Phone interview, I was very confused as to what the interviewer was saying. I was called sharply on time, and was introduced by the guy who leads the mobile apps. His question to me was very confusing and I did not know exactly what he was asking me for, but as he explained through examples I got a good gist of what he was asking. This however, took a lot of time, and I lost a lot of time to do my test.

I've got reached back by an email in few days after i applied online, i later got rejected after a behavioral phone call which i got a few days later.
