Detailed, specific guidance on the Shopify Data Scientist interview process - with a breakdown of different stages and interview questions asked at each stage

The role of a Shopify Data Scientist

Data science is a crucial part of Shopify’s mission to make commerce better for everyone. Data science at Shopify principally includes two types of work: building products directly backed by data (e.g. machine learning models), and listening to their voice to figure out what to build and how to build it. 

Shopify looks more for Data Scientists who have solved challenging problems than those familiar with specific tools or technologies. They are looking for talented data scientists to help them better understand their merchants and buyers.

Shopify hires Data Scientists across the company and there are different seniority levels depending on the scope and expected impact.They have Senior and Staff level roles and some openings for Data Science Managers. For instance, there was recently a role in Merchant Services - the goal being to give small businesses targeted advice that can help them better compete with larger ecommerce players. Given the scope and complexity of this undertaking, this was a Staff level role.

As a Data Scientist, you are expected to play a crucial role pushing forward product development across multiple domains. Data Scientists do this by informing high-level product strategy and execution, building a strong and broad operating picture allowing Shopify to move quickly, and/or improving underlying algorithms, heuristics and rules powering individual products - making the Shopify Data Scientist a sought-after role!

You'll find plenty of opportunities along with the Data Scientist role at Shopify, and you can easily apply to roles directly on the site.

  • Brush up on your SQL skills and make sure you have a solid understanding of software engineering fundamentals.
  • Being proficient in Object Oriented Programming will give you an edge in the interview process. This is because Data Scientists at Shopify are expected to be pretty much “full stack” in nature.
  • Showcase your experience with applied statistics and your ability to solve quantitative problems.
  • Be prepared to explain how you've turned analytical insights into clear recommendations, and demonstrate your ability to communicate effectively with technical and non-technical stakeholders.
  • Highlight your understanding of dimensional modeling and the ability to scale ETL pipelines.
  • Having experience launching productionized machine learning models at scale will give you an edge over the other candidates.
  • A Domain experience in e-commerce, marketing or SaaS can help to tailor your approach in a specific industry.

Shopify Data Scientist Interview Guide

As a part of the Shopify Data Scientist interview, the candidate will need to go through multiple interview rounds:

1. Recruiter call or Behavioural Round - The first round is to have a quick discussion about your work experiences and the roles you’ve had in the past company.

2. Pair Programming or Coding round - The second round is to test your data science concepts and SQL and Python-related concepts. This is to test your analytical skills and to see the approach you take to solve the given problem.

3. The final round of Shopify Data Scientist interviews will usually be a combination of technical rounds and behavioral rounds. You will have a panel of interviewers (often senior data scientists) who will assess you across a range of skills and experiences. The skills you will be likely tested on are: product analytics, metric analysis and behavioral/leadership skills.

Shopify Data Scientist - Peer Programming or Coding Round


The second round can either be a Pair Programming round or a Coding round. Candidates have reported experiencing either.

If you encounter a Pair Programming round, here’s what you can expect: You will be paired with a data scientist and will be given a dataset to work on and solve the given problem. The dataset problem could be a classification or regression problem. Here your analytical skills will be tested along with the approach you take to solve the given problem. A DS candidate reported being asked to work on Map Reduce as part of their Pair Programming exercise, for instance.

If you encounter a Coding Problem, here’s what you can expect: It will be focused on Object Oriented Programming in python. You will be asked to fix bugs and add more functionality to the code. There will be some questions related to Data Science concepts and questions related to Python and SQL.

Interview Questions

  • What is wrong with the given code and how would you fix it?
  • What is your experience with OOP using python?
  • Given a list of (date, duration) tuples, how would you filter by time period and calculate summary stats (average, rolling sum)?
  • Program Conway’s game of life in Python.
  • Basic operations on lists with some corner cases to think about.
  • Write a recursive function in Python.
  • Create an object class in Python to iterate over sequences.

Shopify Data Scientist - Final Round Interviews


Final round will usually be a combination of Technical Rounds and Behavioral rounds. You'll have a panel of interviewers (often senior data scientists) who will assess you across a range of skills and experiences.

You'll be tested across problem solving skills (often focusing on data analysis and visualization); you'll also be tested on product analytics and metrics; and finally - you'll face several behavioral questions.

A key part of the final round is what Shopify calls the "Life Story" round. This round is about your career journey such as what you have done till now. What are your strengths and weaknesses? Your interviewers will emphasize on what led you to this point in life and why you want to work at Shopify as a Data Scientist.

Some candidates have reported that they had this part of the conversation directly at the recruiter stage and didn't face this again during their onsite. In this context; we'd recommend being prepared for questions such as "What's your background and how do you think you reached this stage" up front, even for the recruiter rounds.

Interview Questions

  • How do you analyze if a product is successful?
  • Explain how data manipulation works in pandas.
  • How to create a simple string manipulation in Python?
  • What is a median? How would you go about calculating a median from a dataset too large to store in memory?

Shopify Data Scientist Interview Tips
