So I did an interview today and the problem was given a = 1 2 3 and b = 2 3 write code that finds the common elements.

I asked what the data structures are and they said it can be whatever so I said cool then we can use sets and do an interception to get unique elements.... this was in Python... but for the life of me I couldn't remember what the intercept notation was... and brought that up hoping they're give me a hint haha.

So I ended up writing a 8-9 line solution for what could've been a one liner fml: return a | b.

All because I didn't know the notation and still needed to give them something. Painful to write when I knew I was reinventing the wheel. Sign

I almost never use sets so this was heartbreaking hopefully I still get an offer!

How bad of a fail is this in y'all opinion?

    Hmmmm. Try writing 15 lines for something that doesn't completely work, but the answer can be done in 1 line.

    Fml

    @Stuxnet that helped (: and ouch. I've done it too. Isn't it a pain at the extra work done just from ignorance?

    @Stuxnet but you stuck with it right? I think everyone has had a moment like that at one time. Hopefully haha

    @dalastTomCruise That happened last semester. In the intro to CS class.

    But so far still sticking with it. I'll see how it's going after 5 or 6 classes (the required for a minor in CS)

    @dalastTomCruise I don’t think it was ignorance on your side. You just didn’t remember the exact syntax and with 30 seconds on google your problem would have been solved as you knew what you had to do :)
    Hope they will get that and that they saw your imagination on working around your “memory flaw” :)

    Looking up docs for stuff like that is so normal that I'd be upset if they didn't allow it in an interview unless it was pseudo code.
