I applied online. I interviewed at Amazon (Seattle, WA)
Interview
recruiter reached out to me, scheduled for tech screen
was told it would pure machine learning concept, no coding.
actual interview (surprise !!!!!)
recruiter mail
scheduled the first screen ( then interviewed didn't showed up)- suppose to be pure ML round.
last moment change a day before with new interviewer and coding round. WTF!!!!!!
Interview questions [2]

log reg and the descision boundry
gausian plane
normalization
random forest and types of trees.
cluster and regression
supervised and unsupervised learning
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.
