I applied online. The process took 5 weeks. I interviewed at Amazon (San Francisco, CA) in Jun 2015
Interview
An engineer from the team called me for an phone interview. He very quickly asked a few questions about my resume and then he opened gave me a collabedit link and asked a coding question. It was a rather easy one. Engineer was very friendly and helpful. After I solved the question, he asked a lot of general questions about multithreading and object oriented design.
