J'ai postulé via la recommandation d'un employé. J'ai passé un entretien chez Amazon en oct. 2020
Entretien
The first round was a phone screening. I was asked about my work experience and a coding question on count of frequent words in a stream of text.
The virtual onsite interview had 6 rounds of 1 hour interviews.
Round1: Leadership principles and then a coding session. The question was to get the count of rows based on a criteria.
Round 2: Technical presentation on a project you did in the past
Round3: Leadership questions and questions on data science scenarios. Try to ask as many as questions you can.
Round 4: Leadership questions and basic machine learning concepts like difference between bagging and boosting, What is naive bayes, explain p-value in layman terms, what is a normal distribution.
Round 5: LP questions and very simple sql queries
Round 6: Completely leadership questions
Questions d'entretien [1]
Question 1
What is difference between bagging and boosting
What is naive bayes algorithm
Explain p-value
Explain Bayes theorem
Explain bias variance tradeoff
Example of a high bias and high variance models
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.
