I applied online. The process took 2 months. I interviewed at Meta in Nov 2021
Interview
Two technical interviews 45 min each, two medium leetcode tasks, at the beginning of the second was asked behavioural questions like "what was the project you were working on", "tell me about yourself"
Straight forward leetcode questions and talk about school projects, including typical system design questions to test analytical and academic understanding. Just read through glassdoor examples and you should be fine. Note that you need to practice programming of a language of choice so that you are familiar and proficient
I applied online. The process took 3 months. I interviewed at Meta (London, England)
Interview
OA assessment with 4 questions in ~1 hour, then a technical phone screen with a recruiter (2 medium Meta-tagged Leetcode questions in 45 minutes). Overall, I felt like if I prepared slightly more, I could have gotten the offer.
