Entrevista
The hr people are nice and efficient. It is a very small group of Amazon made up by a group of SDEs who think themselves know Statistics. Their knowledge on Statistics come purely from experience so it is very difficult to explain to them using the terms I learned in college. They think it is me that do not understand Statistics but it is actually them. They obvious only want computer science people because they themselves are. But what they really need is real Statisticians who have a formal education from college on Statistics.

They asked a lot of details and they do have a certain answer that they want to hear.
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.
