I applied online. The process took 2 days. I interviewed at Meta (New York, NY) in May 2015
Interview
Roughly 45 min phone interview starting with introducing yourself and your working experience,
Academic experience etc.
Then a coding exercise using an online document sharing with a C language algorithmic question.
i.e Without using STL or other external libraries.
The question is a basic String Algorithm question.

Question 1
How do you answer if someone asks how long a deliverable or project will take?
The entire process usually takes 3–8 weeks, depending on scheduling and the specific role.
