I need to get this off my chest...

So I was interviewing for an intern position at a procurement analytics company recently, we had an initial conversation on the phone where the engineer said "spend classification".I heard it and ask for confirmation "spam classification?"The engineer reply "yes spend classification".

So there I was, for the next 48 hours before the interview, trying to figure out the scenarios spam classification is used in the context of procurement analytics (what I got was a super reaching scenario but it was fun).

During the interview, I was trying to talk about the projects I did that could be useful for spam/data imbalance usecases instead of a few other things that I did which are much cooler. At the end, I ask about why they are doing spam classification for context of procurement analytics and they asked where I heard that from. I was like you guys said "spam classification". Then it dawn on me and them that I misheard "spend classification" as "spam classification".

We had a laugh, I talked about the scenario I mentioned and talked about Siamese network but I still felt damn embarrassed about it since I could have been talking about other projects.
