Company: Amazon

Location: Santa Barbara, CA

Role: Data Scientist

Level: Mid-Level

Outcome: Rejected

When did you have this interview?: Last Month

Very smooth process. I sent my resume 6 months ago (Dec 2020) and got a callback (May 2021. Contacted by Senior Recruiter(no specific questions, just talk) and then passed to the technical part by phone(no video). Nice attitude, very positive experience. Asked a lot about my previous experience and deeper into ML. How decision tree built, overfitting, k-means, bias-variance trade off etc. Failed on the python part. No SQL though. In a week got a rejecting email.

What kind of technical questions did you get asked?

Suppose you have a list of strings, each of which is an English sentence. Output a dictionary outdict that maps a key n to the list of words that occur in n different sentences. E.g. Input: strlist = [ “The cat ate the fish”, “The cat saw the roses”, “The roses are red” ]
