I applied through an employee referral. I interviewed at Amazon (San Jose, CA) in Jan 2022
Interview
Very tedious. Basic SQL questions and merge operations in pandas. Coding basic functions in pandas in the beginning and linear and multivariate analysis questions. Also discussed correlation and heatmap PCA dimensionality reduction
Interview questions [1]
Question 1
Multivariate analysis, Pandas merge operations and apply functions.
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.
