I once got a surprise leetcode coding interview for a security testing role that mentioned proficiency in a coding language or two as desirable but not essential.

I come from a math background rather than CS and code for fun / personal projects, so don't know the 'proper' names for some algorithms from memory. I could have done some leetcode prep / revision if I had any indication that it was coming up, though the interview was pretty much a waste of time. I told them that and made a stab at it, though they didn't seem interested in engaging at all and barely made eye contact during the whole interview.
