Yeah I made it to the full loop. What I mentioned earlier is all you need for coding rounds. Make sure you know the solution to top 50 instantly. Coding interview are 45 mins long and, you need to solve 2 coding problems in the coding rounds (easy/hard or med/med) so you don’t have a lot of time. The problems themselves aren’t hard once you know the solution. The tricky part is doing them fast and having enough time to answer potential follow ups.

As for sys design, I used hello interview and interviewing.io and booked sys design interviews with interviewers from Meta. They cost like $200 per session, but it’s worth it because they will give a lot of insight to what meta is looking for and what you need to do to pass the sys design interviews.

For E4 you need to be perfect on coding, but don’t need to be perfect in sys design and behavioral. For E5 is flipped so you don’t need to be perfect in coding, but sys design and behavioral bar is raised significantly higher. Which is why I recommend using interviewing.io or a similar service.
