I applied through an employee referral. The process took 2 months. I interviewed at Amazon (London, England) in Dec 2019
Interview
I was referred by a friend. The entire process took less than 2 months.
Received an online test after submitting my application, the test included behavioral questions and tasks related to the job. After a monthlong waiting, it came with a language translation test which was not so difficult just have to translate what exactly the word is into English, no words should be omitted or mistranslated. You don't have to score perfectly, but just don't make big mistakes. Then after completing the language test, I had an interview with one of the investigation managers. Just to notice, the recruiter will send you an interview prep guide to help you prepare the interview, which is quite nice and help you prepare other interviews as well. The interview was fairly a standard one and questions were based on 14 leadership principles of Amazon, so you'd better read it thoroughly if you have an interview with them.
There are 2 rounds of assessments. One is on language ability, including listening, reading, speaking. The other one would be more focused on attitude test. There will be some simulated situation on actual working task with time limit.
Smooth process, straight questions, helpful staff and everything is discussed thoroughly before the start of the employment. I appeared for an online test and after being shortlisted, the HR contacted me for the interview process
Just a written test on basic investigative skills and communications, including email drafting and navigating their platform. Also they tested you your priority over some tasks happening at the same time. No preparation needed.
Email confirmed the offer after months.
