Google is all-in on this too, but in my experience Apple is way worse at that kind of interview just like you experienced. I had one interviewer ask me to write strstr but then insist that boyer-moore could not possibly work. I don't expect every engineer to be familiar with common CS algorithms but whew, if you're gonna use them as an interview question...

The other parts of the interview weren't as bad but they also weren't great. Expecting you to know what happens when you export an int as 'main' instead of a function, for example - you can certainly figure that out from first principles or happen to know, but why should you?

It's sort of a "when a company shows you who they are, believe them" situation - even when I did get offers, seeing this reduced my confidence in the company.
