Candidatei-me por indicação de um funcionário. Fui entrevistado pela Amazon (Seattle, WA) em jan. de 2021
Entrevista
The interviews are virtual due to Covid-19. So the normal call interview was more like an in person interview.
The interviewer went over my CV and asked for every project I worked on. He also asked about my PhD thesis, which was not related to the job at all.

Coding question (Python):
Assume you have a file containing data in the form of
data = [{"one":a1, "two":b1,...},{"one":a2, "two":b2,...},{"one":a3, "two":b3,...},...]
How could you split this data into 30% test and 70% train data?
Fiz uma entrevista na empresa Amazon (Seattle, WA).
Entrevista
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.
