There is no shame in leaving after only 2 months, if you're really not enjoying. I've just left a job where I had to do nothing, the last months of the year was horrible. After many months of free time, I really had no idea what to do, days were boring and long.

I would start interviewing as soon as possible. Don't worry about blowing the interview at Amazon, you can try again in 2 years. You'd do well to read the interview questions at glassdoor.com, they often ask the same questions (I interviewed there), but don't think that you should postpone it and spend the time learning. Just apply again in a year, it's not like you are a very capable learner when you're burned out.
