Strava's coding interviews are generally on par with medium to hard LeetCode difficulty, similar to other top tech companies. The key difference is a heavier emphasis on clean, efficient code and explaining your thought process clearly, as they value collaboration. Expect problems that can involve graph traversal or data processing, often with a slight nod to fitness/activity data.
For SDE roles, focus heavily on system design fundamentals (scalability, APIs, databases) as Strava handles massive global data streams. For senior roles, be prepared to discuss trade-offs in distributed systems and cloud infrastructure (AWS). Also, understand core concepts like REST APIs, caching strategies, and data modeling for time-series or geospatial data, which are relevant to their product.
The Bar Raiser is a unique, deep-dive behavioral and leadership round conducted by a senior leader from another team to ensure hiring standards. Prepare by rigorously mastering Strava's Leadership Principles (like 'Athlete First' and 'Community Focus'). Use the STAR method to structure stories that demonstrate these principles, especially around influencing without authority, handling ambiguity, and building community.
A frequent mistake is treating the interview as purely a coding test and not demonstrating product sense or passion for Strava's mission. You must connect your technical solutions to the user experience and Strava's athlete community. Also, failing to ask insightful questions about their specific engineering challenges (e.g., handling peak event data from a race) shows a lack of genuine interest.
The process usually takes 4-6 weeks. Stages typically include: an initial recruiter screen, a technical phone screen (coding), a virtual onsite with 4-5 rounds (2-3 coding, 1 system design, 1 Bar Raiser/behavioral), and finally team matching and an offer call. Timelines can stretch if there are many candidates or during holiday periods.
SDE-1 (L4) focuses on core DSA and clean implementation. SDE-2 (L5) adds system design fundamentals and expects more ownership in behavioral stories. SDE-3 (L6) requires deep system design expertise (architecting features, trade-off analysis) and behavioral examples demonstrating technical leadership, mentorship, and strategic project influence. The bar for scope and impact rises significantly with each level.
Use LeetCode (focus on mediums/hards) and Grokking the System Design Interview for fundamentals. Crucially, read Strava's engineering blog and tech talks on their website to understand their stack and challenges. Practice explaining your code aloud as if to a teammate. For the Bar Raiser, dissect every Leadership Principle with 2-3 personal stories that have clear metrics.
Be a power user! Mention specific features you use (Segments, Routes, Heatmaps) and suggest thoughtful, user-centric improvements or ask about their engineering challenges. Weave your passion for fitness/community into your behavioral answers. Ask your interviewers questions about how their work directly impacts athlete experience or community building, showing you see beyond just the code.
