I had two rounds of online assessments and one round virtual interview. Online assessments were time limited with debugging questions, logic questions and coding problems. Virtual interview was 45 mins and the interviewer asked some behavioural questions plus some tech questions.
I applied online. The process took 3 months. I interviewed at Amazon (Seattle, WA)
Interview
For me the process took 9 months or more. I pushed back my online assessment because I wanted to study very well. I passed the online assessment as well as the phone interview. I got an onsite interview in Seattle. I did well in the interview. However, I still didn't get an offer. They gave me a stranger reason, your level is an SDE2, but you didn't quite fullfil that even though you did well on the questions. I was like, I can go for an SDE1, but they were set on not giving me an offer. To be honest, I don't work with people who don't want to work with me, so it's all good. One of the interviews was very robotic and didn't really interact nicely. I'm kind of surprised that someone with mediocre communication skills is assessing a candidate. Whatever. It's all good in the end. Something much better is coming my way.
