568 ruby rails interview questions shared by candidates

Most difficult was probably a moderately complicated SQL query.. at the time I had been doing lots of rails and my head was not in the pure SQL mode at all.

I got the entirety of the idea correct and the majority of the syntax correct, but some of it was a little railsified out of lack of wholly memorized SQL syntax.
