I understand what Function.prototype.call() does (and I'm an amateur ruby dev), I don't know what .bind() does but could go for a wild guess. Explaining something like this, might be more tricky. However with 10+ years of experience I'd expect someone to make rounds around things like that. On the other hand an excellent hire might be a cheat that put the effort to become a good developer once he joined the company or... You might hire a very promising young man who (because this or that) he ended up being a bad hire.
