I applied through an employee referral. I interviewed at Meta (Dublin, Dublin) in May 2017
Interview
I have successfully passed initial screening by recruiter and two rounds of online interviews with different engineers and was invited for an onsite interview, which was held in Dublin.
Things to be discussed were quite interesting as a whole, and I got almost positive feedback, although I failed coding interview - as I was supposed to write a piece of well-known computer game and I have chosen to do it in C and (from interviewer's point of view) have selected somewhat non-optimal data structures for it.
I had two screening rounds and 3 interview loop rounds, Meta leetcode questions, systems design can be extensive. Questions can be repeated so look out for all the available questions online. Systems debugging is a very important topic
