I don't think this approach would scale, due to the time investment required. It also suffers from making it hard to compare one candidate to another in a fair way, unless you have everyone fix the same bugs. Having a bunch of canned bugs to be fixed doesn't seem much better than asking a CS puzzle.

This individual joined Google in 2009, and left before he'd been there 3 years. He's in no position to be waxing nostalgic about the "good old days" of Google.

I think the convention for chord notation is different to the convention for scale degrees. The 7th note in C major is B, but a C7 has a Bb.

Sorry to be pedantic, but a 9th chord actually has a 9th and a _flat_ 7th. For example C9 has the notes C-E-G-Bb-D. 9th chords are part of the dominant group, not the major group.

A chord with a 9th and a 7th is a _major_ 9th. For example, the chord C-E-G-B-D is Cmaj9 (sometimes written C triangle 9).
