I’m so mad that no job interview has ever asked me that question about what my greatest weakness is. I’ve had “music in the Dorian mode, tall men in dark suits, and anything combining the tastes of coffee and chocolate,” cocked and loaded for about a decade now, and I still can’t come to terms with the fact that I’ll never actually get to use it.
All my sympathies are with you.
…my go-to-that-I’ve-never-gotten-to-use is “if you flip me on my back, I can’t right myself.”
