1. Introduction to Shopify Interviews

Shopify, a leading e-commerce platform, is known for its rigorous interview process. The company seeks candidates who not only possess technical skills but also demonstrate creativity, problem-solving abilities, and a passion for e-commerce. Interviews at Shopify typically involve a mix of technical questions, coding challenges, design problems, and behavioral inquiries.

Before diving into specific questions, it’s essential to understand that Shopify values candidates who are familiar with their platform, have a customer-centric mindset, and can contribute to their mission of making commerce better for everyone.

2. Technical Questions

Technical questions at Shopify can vary depending on the role you’re applying for. Here are some common questions you might encounter:

Q1: What is the difference between Ruby and Ruby on Rails?

Answer: Ruby is a programming language, while Ruby on Rails (often just called Rails) is a web application framework written in Ruby. Ruby is a general-purpose, object-oriented language, whereas Rails is a collection of tools and libraries that provide a structure for building web applications using Ruby.

Q2: Explain the MVC architecture.

Answer: MVC stands for Model-View-Controller. It’s an architectural pattern used in software design:

  • Model: Represents the data and business logic of the application.
  • View: Handles the presentation layer, i.e., what the user sees.
  • Controller: Acts as an intermediary between the Model and View, processing user input and managing data flow.

This separation of concerns allows for more maintainable and scalable code.

Q3: What is a RESTful API?

Answer: REST (Representational State Transfer) is an architectural style for designing networked applications. A RESTful API is an interface that uses HTTP requests to GET, PUT, POST, and DELETE data. It’s stateless, meaning each request from client to server must contain all the information needed to understand and process the request.

Q4: Explain the concept of database indexing.

Answer: Database indexing is a technique used to improve the speed of data retrieval operations on a database table. It creates a data structure (index) that allows the database engine to find and access specific rows much faster, without having to search every row in a table every time it’s accessed.

Q5: What are the benefits of using GraphQL over REST?

Answer: GraphQL offers several advantages over REST:

  • Flexible data fetching: Clients can request exactly what they need.
  • Single endpoint: All data can be accessed through a single API endpoint.
  • Strongly typed: The schema defines what’s possible, reducing errors.
  • Efficient: Reduces over-fetching and under-fetching of data.
  • Versioning: Easier to add new fields and types without versioning the API.

3. Coding Challenges

Shopify often includes coding challenges in their interview process. These challenges are designed to assess your problem-solving skills, coding ability, and thought process. Here are a few examples:

Challenge 1: Implement a function to reverse a string

Problem: Write a function that takes a string as input and returns the reverse of that string.

Solution (in Ruby):

def reverse_string(str)
  str.reverse
end

# Alternatively, without using the built-in reverse method:
def reverse_string(str)
  str.chars.reduce("") { |reversed, char| char + reversed }
end

# Test the function
puts reverse_string("Hello, Shopify!") # Output: "!yfipohS ,olleH"

Challenge 2: Find the most frequent element in an array

Problem: Write a function that takes an array of integers and returns the most frequent element in the array.

Solution (in Ruby):

def most_frequent(arr)
  frequency = Hash.new(0)
  arr.each { |num| frequency[num] += 1 }
  frequency.max_by { |k, v| v }[0]
end

# Test the function
puts most_frequent([1, 2, 3, 2, 1, 3, 2, 2, 4, 2]) # Output: 2

Challenge 3: Implement a basic cart functionality

Problem: Create a simple shopping cart class that allows adding items, removing items, and calculating the total price.

Solution (in Ruby):

class ShoppingCart
  def initialize
    @items = {}
  end

  def add_item(item, price, quantity = 1)
    @items[item] = { price: price, quantity: @items[item] ? @items[item][:quantity] + quantity : quantity }
  end

  def remove_item(item, quantity = 1)
    return unless @items[item]
    @items[item][:quantity] -= quantity
    @items.delete(item) if @items[item][:quantity] <= 0
  end

  def total
    @items.sum { |item, data| data[:price] * data[:quantity] }
  end
end

# Test the shopping cart
cart = ShoppingCart.new
cart.add_item("Apple", 0.5, 3)
cart.add_item("Banana", 0.3, 2)
cart.remove_item("Apple", 1)
puts cart.total # Output: 1.6
