I applied through a recruiter. The process took 1 week. I interviewed at Meta (London, England) in Mar 2021
Interview
The job required several interviews including technical, theoretical knowledge and culture fit. The process is very lengthy and thorough, however in the tech tests the conditions are unrealistic of a real working environment. It tests you on memorising computer theory rather than solving problems with code, when you work in a field with a vast amount of generalist knowledge it's really not a good use of time to memorise fizz buzz-style assessment solutions.
