Spotify is a global leader in the audio-streaming industry, adept at scaling quickly and achieving rapid growth in users and business. Spotify passed half a billion monthly users in 2023 and are actively working to amplify productivity, quality, and innovation across the organization.
Across all teams, Spotify places a strong emphasis on empowered, data-informed product development. To achieve this, they carry out regular and comprehensive exploratory analyses to better understand their users’ needs, as well as determine how they can deliver greater value through their product offerings. As such, Spotify assesses its job candidates in various technical fields such as databases, algorithms, machine learning, and analytics. Here’s how Spotify conducts their data science interviews.
Spotify’s interview process is geared towards evaluating a candidate’s skills, experiences, and fit for the role. Here is a breakdown of the process based on various sources:
This process is routinely described as quite rigorous and is designed to thoroughly evaluate a candidate’s suitability for the role at Spotify.
Preparing for a role at Spotify, especially in a capacity that involves database management and operations, means anticipating a range of questions that test your technical competence and problem-solving skills.
Here, we delve into three questions that mirror real-world scenarios you might encounter on the job. These questions aim to evaluate your understanding of database operations, data retrieval, and system design, all crucial for ensuring seamless user experiences and efficient data management at Spotify.
Let’s say you work at Spotify. We want to design a relational database for storing metadata about songs. We want to include metadata like song title, song length, the date the song was added to the platform, artist, album, track number (on the album), the song’s release year, and its genre.
How would you go about designing this database?
Given a table of
song_plays and a table of
users, write a query to extract the earliest date each user played their third unique song. If a user has listened to less than three unique songs, display their name but with a
NULL date and song name.
Design a podcast search engine that can search through podcast transcripts and metadata.
Spotify, being at the frontier of the digital music industry, necessitates from its candidates a strong foundation in coding and algorithms for many roles. The questions listed below reflect issues that might arise during Spotify’s day-to-day operations or in the process of developing new features.
Mastery in solving such problems not only demonstrates your technical prowess but also your ability to contribute to Spotify’s ongoing mission to provide seamless and personalized music streaming experiences.
You are given an integer
N. Your task is to write a function that returns a list of all prime numbers up to
N. If there are no prime numbers less than or equal to
N, return an empty list.
You have a
song_plays table with songplay details and a
users table with user information. Write a query to find the earliest date each user played their third unique song. If a user has listened to less than three unique songs, display their name but with a
NULL date and song name.
Given a list of strings, your task is to write a string parser that checks if the opening and closing characters or tags match in each string. The parser should return a list of booleans, stating whether each string’s integrity was verified.
Machine learning is at the heart of Spotify’s personalized user experience, from recommendation systems to search functionalities. The questions here highlight common challenges faced in deploying machine learning solutions in a real-world, large-scale environment like Spotify.
Your responses will be instrumental in demonstrating your readiness to contribute to Spotify’s machine-learning projects, ensuring that the platform continues to evolve and cater to the diverse musical tastes of its global user base.
Consider the task of designing a search engine for podcasts. This engine should utilize both the transcript of the podcast and any associated metadata. Explain your approach.
Imagine you are tasked with building a machine learning system to generate Spotify’s Discover Weekly playlist. Describe your approach and the steps you would take.
Discuss the concept of “bootstrapping” a dataset. Provide an example of when it would be appropriate to bootstrap smaller samples from a larger dataset and discuss the advantages and disadvantages of this method.
Spotify’s dynamic structure demands a rigorous understanding and application of analytics and experimental methods to drive informed decisions and innovative solutions. These questions are designed to gauge your analytical thinking, your ability to derive actionable insights from data, and your aptitude for designing, conducting, and interpreting experiments in a complex digital ecosystem.
Spotify will look to see how you can be additive to their data-driven culture, promoting continuous learning and improvement.
You work for a social media company that has recently launched in a new city. From January to March, there has been a steady increase in new users, but the average number of comments per user has been slowly decreasing. What could be causing this trend, and what metrics would you examine to understand it better?
The company is considering monetizing its web traffic by inserting web banners into its reading content. How would you measure the effectiveness of this strategy?
The company is contemplating expanding into the podcast market. How would you measure the potential impact on customer lifetime value?
For practicing Analytics and Experiments, consider using the product metrics learning path and the data analytics learning path. These resources will help you understand and solve complex problems related to product metrics and data analytics.
