Maybe you all just weren't good enough. That's OK, not everybody is the creme-a-la-creme. Look at Google's market cap and Android and Chrome's growth (not to mention their dominance in search and advertising)... Google doesn't need you, and that's why they didn't hire you.
You can cry a river about how Google is "failing" because they didn't hire you... but I think their shareholders (who Google makes very rich) would laugh right in your face and be glad that they didn't hire a whiner like you.
