Snap Interview Process

The interview process at Snap is typically split into 3 stages: a phone call with a recruiter, a technical assessment, and a final round of 4–6 interviews all on 1 day. Expect to be tested on your technical prowess, as Snap interviewers look for accuracy in results more than anything else.

The Snap interview process typically takes about 3–4 weeks and involves:

Recruiter phone screen,
Technical screen,
Final round.

Recruiter phone screen

This is a 30–60 minute phone call with a Snap recruiter. You’ll likely discuss your resume and any relevant experience. Expect to answer why you want to work for Snap and this team, some basic situational questions, and discuss the rest of the interview process.

Technical screen

The second round of the interview process at Snap is a 60-minute technical screen with an engineer or the hiring manager. You’ll likely get 10–20 minutes to answer behavioral questions or questions about your background and then the rest of the hour to complete a coding challenge.

For non-technical roles, such as a PM role, expect a conversational interview with the hiring manager.

Final rounds

For your final round at Snap, expect 4–6 hour-long rounds focused on your domain. Your final round at Snap usually takes place all in 1 day. The final round can be conducted virtually or in person, depending on the role and your location.

Something unique about Snap’s final round is the lack of a standalone behavioral round. Instead, you’ll likely get 10–15 minutes of behavioral questions in each of your other final-round interviews.

Behavioral

The behavioral round at Snap is incorporated into all of your other final-round interviews. You won't have a dedicated behavioral round. Expect 10–15 minutes of behavioral interview questions included at the beginning of each of your other rounds to assess your culture fit and values.

Consider Snap’s core values ahead of time: we are kind, we are smart, and we are creative. Prepare anecdotes that demonstrate these values in yourself and your past roles to demonstrate your culture fit at Snap.

Coding

Most engineers get 2 coding rounds at Snap. Expect hour-long interviews focused on solving traditional coding problems of medium difficulty. Since most coding roles at Snap don’t require a specific language, a strong knowledge of software engineering is most important.

Snap looks for engineers with a range of skills, an ability to write and review exceptional quality code, and a strong background in ML.

System design

The system design round is a standard whiteboard interview. You'll likely get a design question that involves ML because of how pivotal ML is in Snap’s products.

Expect a high-level problem with real-world Snap use cases, focused on scalability, latency, storage, distributed systems, API design, and user experience. To prepare for real-world questions, get to know Snap’s products, Snapchat, Spectacles, and Snap AR, and read Snap’s engineering blog.

Machine learning

Snap’s machine learning round is a 1-hour interview that assesses your understanding of ML fundamentals and previous experience. The ML round at Snap depends on your interviewer, so it can involve a technical ML assessment, or be more conversational. For example, the interviewer may ask you to present a past ML project.

Expect questions on standard ML topics such as metrics, unbalanced data, overfitting, and optimizers. If presenting a past project, expect to discuss the problem statement, data collection, feature engineering, model optimization techniques, and the model selection process.

Product management

The product management round at Snap involves interviews with 4–5 cross-functional stakeholders, so your interviewers depend on the team associated with your role. Remember, you’ll also get behavioral questions throughout your PM round since it’s not a separate round at Snap.

To prepare, study strategy, product design, and execution questions. Practice technical questions related to the team. Study up on how ML is used in the product.

Snap Interview Tips

Snap values creativity.

As the creator of Snapchat and Snapchat filters, you can see how creativity and fun are driving forces behind Snap’s social products. Stand out by showing off your innovative side in interviews. Think outside the box in open-ended questions, like in your system design interview.

And discuss past creative projects you contributed to in your conversational interviews. Years of past practical experience are highly valued at Snap.

Snap’s interviews are highly technical.

Perhaps on the flip side of creativity, Snap interviewers assess candidates on the accuracy of the technical portions of the interview process. While other companies often focus on critical thinking and problem-solving skills, expect to be almost purely assessed on the accuracy of your results at Snap.

Brush up on coding, ML coding, and system design before your interview.

Know Snap inside and out.
