I had a phone / screenshare interview with Google one day. Asked me to solve a Soduko problem (I have never done a Sudoko until that point). Didn't get it.

Half an hour later wandering done the street a very elegant solution came to me. I wouldn't say I am bad algorithmic stuff, but as I never practice it's pretty random whether I will get during an interview. "Luck" as you say.
