11+ YoE

I've been to a Facebook interview for an E5 role. I got to the final rounds and got strong positive signals for behavioural and system design interviews but mixed signals for coding. The recruiter then asked me to do one more coding interview, all or nothing. It was very close, but I bombed on this interview.

The process was quite positive and helped me take Facebook from a pedestal as I got close to an offer.

I'm a Staff+ now and the same recruiter came to me with another opportunity for E6, and it looks like the interview process is different.

For the phone screening, it's not only code but code + behavioural in 1 hour (it looks like it's just 1 question rather than 2, but I saw a folk here having two questions anyway).

If I got yes, for the final round, it'd be 2 coding + 1 behavioural + 2 system design.

I'm quite confident in behavioural and system design interviews for E5 positions as I'm aware of the expectations and I am an interviewer in my current company. But I'm unsure about E6 expectations and what I should aim for to stand out (I haven't interviewed any other Staff engineer yet either).

Can anyone help me on setting my expectations for this interview? What's the breakpoint between E5 and E6 they're looking for?
