The Amazon Data Scientist Interview Process

There are 3 stages of the Amazon Data Scientist Interview Process:

• Stage- 1: Recruiter’s Call
• Stage- 2: Phone Screening
• Stage- 3: On-Site Round

Stage 1: Recruiter’s Call (30-Minutes)

The first stage of the Amazon Data Scientist interview is a 30-minute recruiter screening aimed at assessing the candidate’s role-fit, culture-fit, and logistics.

 Prior to the call for the Amazon Data Scientist interview :

 In the applicant tracking system (ATS), the recruiter sees your job application, which includes a resume and optional cover letter. Your application is ranked algorithmically depending on how closely your qualifications match the job descriptions. Recruiters will usually contact applicants with the highest ranking first.

 During the call for Amazon Data Scientist interview :

The recruiter will structure the meeting in the following manner during the call, which will last roughly 20 to 30 minutes:

• Introduction: The recruiter will go through the role expectations and team in further depth.

• Background information for candidates: This is your chance to tell us about yourself. “Tell me about yourself,” the recruiter will inquire. You can give a high-level overview of your academic and professional backgrounds. “Why do you want to work at Amazon?” is one of the follow-up inquiries. 

• The recruiter will normally inquire about the following: What city are you in? What are your technical interview availability? 

• Follow-Ups – The recruiter will outline the following steps, including when you should expect to hear back and how to prepare for technical rounds. This is your opportunity to ask as many questions as possible in order to plan out the technical interviews from beginning to conclusion. The more information you have, the better prepared you will be for interviews.

After the call Amazon Data Scientist interview :  

Following the call, the recruiter will contact the hiring manager with remarks on the candidate’s background, technical screening, logistics, and cultural fit. The recruiter and hiring manager will move you to the first technical round if they believe you have promise.

Stage- 2: Phone Screening (45-60 Minutes)

The technical phone screen for Amazon Data Scientist interview is used to determine a candidate’s communication skills as well as technical aptitude in coding, SQL, statistics, and/or machine learning. The technical screening for Amazon Data Scientist interview takes 45 to 60 minutes and is conducted by a hiring manager or a senior data scientist, just like at other tech organizations. The interview questions change depending on the role, level, and team. In general, expect inquiries about past project experience, coding, SQL, statistics, machine learning, and/or Amazon’s leadership values. 

For example, a phone screen for Amazon Data Scientist interview might look like this:

1. First 5 minutes- Introduction

2. 20 Minutes- Python Coding 

3. 15 Minutes- ML breath question or a case problem 

4. Last 5 minutes- Q and A with the interviewer

In Amazon Data Scientist interview leadership principles are often asked by the recruiters.

Stage- 3: On-Site Round (4-5 Hours)

Amazon Data Scientist interview, On-site round is the most difficult part of the procedure. You’ll be doing back-to-back 45- to 60-minute interviews with a little break in between. Overall, the interviews cover a wide range of topics, including statistics, SQL, coding, machine learning, and leadership principles.

The capacity to maintain concentration and remain calm under pressure is necessary to succeed in the on-site stage.

Let’s take a look at the rounds from the Amazon Data Scientist interview on-site stage. The rounds and questions differ depending on the function (data scientist vs MLE vs applied scientist vs research scientist).

• Machine Learning: Questions on machine learning, deep learning, and case studies. The questions could be domain-specific depending on the responsibilities. For example, the MLE – Search or Applied Scientist: Search might be used to test knowledge of NLP and how to rank theories and case issues (e.g., how would you address a cold start problem?).

• Statistics:  Extensive coverage of statistical theory, probability, regression modeling, and experimentation, as well as case-based problems. The principles of statistics should be studied by data scientists. Expect breath-style questions like “What is the p-value?” and case-style inquiries about Amazon’s product design experimentation.

• Coding: Algorithm and data structure issues are common in MLE jobs. You can expect simple algorithm inquiries that need text and/or integer manipulations from data scientists. Expect data manipulation problems that require you to manipulate a table using either vanilla code or a third-party library. Given that you are using a programming language of your choosing, such as Python or R, these inquiry types are analogous to SQL table manipulation.

• SQL: The SQL round is common and expected in all FAANG interviews. In essence, you’ll be given a collection of tables and one to three problems to answer using SQL clauses like JOINS, WHERE, and GROUP BY, as well as window functions like AVG and SUM.

How to Prepare for Amazon Data Scientist interview

 Now that you are familiar with the Amazon Data Scientist interview. Let’s look at the ways to prepare for it. 

• Do you have knowledge about Amazon’s culture?

Your work environment plays a crucial role in the quality of work and your mental health. Because Amazon is so prestigious, it’s easy to assume that you should apply without thinking things through. However, it’s crucial to realize that a job’s prestige will not make you happy in your day-to-day work. It depends on the type of work you do and the people you work with.

Talk to anyone you know who works at Amazon or used to work there as a data scientist or in another job to get a sense of the culture. The leadership concepts we covered earlier can help you anticipate what to expect, but nothing beats speaking with an insider.

Here is a recommendation for you: Inside Amazon

Learn and practice window functions as well as related functions (aggregates, ranks, and statistics creation). In the coding rounds, these are frequently requested questions.

Combining many tables and seeing the outputs can help you practice joins and the various types of joins (left, right, inner, outer). In SQL coding interviews, joins are always required.

Finally, understand how to manipulate date and time ranges and handle time series data, as they can be explicitly requested in inquiries about orders and shipment.

In addition to these technical features, you should review the principles of data structures, algorithms, and statistics. These will help you with the interview’s theory sections. 

Finally, behavioral questions need you to respond honestly and directly to the point; as a result, double-check your CV and make sure you understand everything on it.

Conclusion
