Basic exposure to full-stack work, even if your focus is mainly Backend or Frontend. 🪜 Hiring process We’ve designed our hiring process to be close to real engineering work. We try to avoid trivia-heavy interviews and artificial take-home exercises, and instead focus on how you think through product problems, technical trade-offs, ambiguity, quality, and the use of AI as part of modern engineering.
