Need advice for onsite interview at Meta

- The two questions are usually medium level, they occasionally will ask a hard question but expect it to take the whole time and likely expect you to solve with brute force first and then work through optimizations, and not expecting you to get the perfect solution but showing a good problem solving process - So because they ask medium questions, they also generally want you to solve all the problems with at least a brute force solution that's flawlessly clean and ideally a better solution that's very clean. Focus on clean code and clear communication. If you crush all the interviews but miss one question in one but we're close, you'll probably get an offer too.
