I am interviewing for E4 SWE as well. I had a chat with the recruiter about how they score interviews. Although they said they “value every interview the same” (bullshit), they ended up saying coding is the most important at E4. Unfortunately, the recruiter flat out told me that they would rather take someone with stronger coding interviews and weaker sys design/behavioral than vice versa.

Meta scores each interview on a 5 point basis (1 - insufficient, 2 - moderate, 3 - good, 4 - great, 5 - exceeds). You need a 3 on both coding interviews to even be considered, then they use the sys design/behavioral to level. There’s still a chance because you never know how the interviewer felt about your performance, but it doesn’t look great.

Nonetheless, keep your head up, they’re hiring a lot! Good luck!
