Not who you asked, but I work full-time as a Ruby dev. Off the top of my head, I don't remember the order of arguments of the #reduce method block (it's the opposite of what Elixir uses), the exact syntax of the throw/catch mechanism (in Ruby this isn't exception handling), the methods and parameters for writing into a file, bitwise operators, I always ask a LLM about packing/unpacking bytes between arrays and binary strings and many other things. I also mix up #include? and #includes? because these differ between Ruby and Crystal, and there's also #includes in Rails (AR).

So, the equivalent of creating a dictionary, yeah, sure. But there's loads and loads of stuff that I only use maybe once a week (and someone else maybe uses daily) and that I'd have to awkwardly Google (I use Kagi btw) even during an interview.

Same reply as above, you'd easily be able to speak to this in an interview and not hit the "fraud" alarm. "I think it's accumulator, element here on reduce, but I may have them transposed."

Your interviewer is probably also questioning if it's (a, e) or (e, a), but you passed the fraud filter.
