Since I had some industry experience, after my phone screens, I had the full onsite interview loop. All interviews involve some coding, but they vary in how much: - 2 ninja (coding) interviews. These are garden-variety programming interviews and can be prepped pretty much the same way you'd prep for Google or any other major software company. - 1 jedi (engineering fit) interview. The jedi is designed to assess whether you'll thrive in Facebook's engineering team. You'll talk about problems you've worked through in the past, engineering decisions you've made, and so forth. You'll likely do some coding, too. - 1 pirate (engineering design) interview. If you're in the product-engineering bucket, you'll probably be asked to design a user-facing product; the interview will range from actual coding to high-level design considerations. New-grad hires (people without significant industry experience) will generally not have pirates.
