I've never gone through a FAANG interview but I have gone through some fortune 100s and never once been asked an algorithm questions. But I have no reason not to believe you about FAANG.
Saying questions asked at that level are not about algorithms was based on my non-FAANG experience. I shouldn't have been so absolute.
But with that said, to back up and restate where I was trying to get. What I was trying to say is that algorithms are table stakes, you should absolutely know them at a senior level but the actually questions you should be being asked should be more advanced than that.
Big difference between FAANG and other fortune companies is that FAANG expect their managers up to very senior level to be technical and be able to code even if they do not code day to day. Other Fortune 100 companies are happy to have non-technical managers to manage engineers with mixed results.
In all SV companies coding interviews are strictly required at interviews at M1/M2 level (up to 60-80 reports) and required at some companies at D1 level (150 reports). CTO at start up with 20-30 reports is M1 and will have to do coding 100% and failing coding interview is automatic no hire.
