I applied online. The process took 2 months. I interviewed at Amazon (Seattle, WA) in Feb 2017
Interview
phone screen by hiring manager, and then technical phone screen, and then onsite interview with 6 persons. asking DS/ML questions, SQL questions, case study, statistics questions. the process was clear but waiting to hear back took like 4 weeks after onsite.
There are three rounds in total. The process begins with a coding round, followed by the main interview loop, where you will meet the team and discuss technical skills, experience, and fit.
First round is fun, second round, which is also the final round involved 5 sessions, with different focus. For some sessions, not be able to present my story completely, time was tight, and interviewers were rushing.
Thrilled to have accepted the offer — the process was tougher than I expected. The first round was primarily technical, where I tackled an A/B testing design question that required detailed metrics and sample size calculations. Later, I faced a SQL query challenge focused on tracking customer purchases over consecutive months. Funny enough, I had spent quite some time on PracHub digging into similar case studies, which really helped me approach these problems confidently. The final round included behavioral questions, and I felt well-prepared overall.
