Amazon QAE 2/ SDET 2

Hi, I have started preparing for Amazon, and I have around 8.5 yoe, as QA/SDET, (no hardcore development background), soon it will be 9 years. I want to know, how difficult the interview process for SDET level 5 and what is the difference between total compensation between QAE 2/ SDET 2 in Amazon? Am I eligible for QAE 3/SDET 3 or 2?
