Things I have screwed up: 1. No ability to do mental arithmetic whatsoever. 2. No ability to write standard template library-based C++ code from memory, except maybe cout and cin. 3. Being late. (3 times at least) 4. Being in a different country and forgetting about it. 5. Trying to sell myself because that is what I was told to do and coming across as unforgiveably arrogant. (a difficult balance) 6. When asked about if I minded the data-cleaning work, which could be boring, I joked that if I was worried about being bored I would have chosen a different career. Maybe this isn't even a joke. Either way, highly offended interviewer. 7. Couldn't really speak the language. 8. When interviewing for a position as a bartender, said I could pour beer. Then proceeded to spray the customers with my attempt when I was asked to prove it. (I was young) However, the bar owner then let me work for free as a trainee for the night, and I got the next job.
