Maybe I'm In a slightly unique position because the role I hire for is "Algorithm Developer", but if you've memorised an algorithm I will keep asking you questions until I find an algorithm that you haven't memorised. I don't care whether you know the "correct" algorithm, I care that you can find a working solution to an unknown problem (since that's literally your job) and I care that you know how to assess the good and bad parts of your solution.
I like this response quite a bit. Sounds like I could forget all the names, be fuzzy on the specifics, but if I've been doing the work it couldn't help but show eventually.
