I applied in-person. The process took 3 weeks. I interviewed at Meta (Dublin, Dublin) in Dec 2019

The process was insightful. All the interviewers were super nice and they paid attention to detail. The interview process starts with HR phone call and some trivia questions revolving around programming, networking and linux. Even at this stage, the trivia questions are deep linux questions.
