There are two rounds of phone interview where the amazon principles are asked relating to your work experience application. Once you pass the two phone interviews the next step is a virtual interview full day.
I applied online. The process took 7 weeks. I interviewed at Amazon (London, England) in Jan 2019
Interview
it was fun and interesting, but the weather that day was awful which sort of ruined my day. Tip by the way, you do not have to dress formal or anything very deliberate, just casual and an attitude to enjoy the process would be sufficient!
Received email from recruiter asking to answer set of questions within 48 hours.
Then was a phone screen interview with someone on the team.
Then was an "onsite" virtual interview with 5 people, one of them being from the AWS team (bar raiser).
