Meta Senior Software Engineer interview questions

Very long and grueling process. They literally give you PDFs of material to study for your interviews. You are expected to do 5 one-hour interviews in a single day, solving programming challenges nonstop the entire time. You get a lunch break but that's also a "friendly interview" with an employee to learn about company culture. They are amongst the highest paying in tech and they know it - you sure have to work to get in.
