Don't feel like a complete loser (yes, that is easier said than done). You failed two interviews, but an equally valid way to look at that is that you go so far as the interview stage at two companies, one of which is legendary for being monsterously difficult to interview for. You just did something 99.9% of the world will never ever have the change to do. Did they tell you why you didn't pass the interview? If so work on that, if not, know that there are tons of companies out there that will want to hire you. I never applied for anything like Google, but I had companies that wouldn't take a second look at my application and companies that spent the entire interview stage trying to wow me to sign the employment contract. Most companies (probably in particular Google) have an employment pipeline that has _nothing_ to do with whether you would be a good employee. Don't be discouraged by a few companies choosing not to hire you.
