The process is thorough and quite lengthy, but you’re well supported throughout. All interviews were conducted virtually and in English.

• Recruiter Screen: An initial discussion with a recruiter to review your background and motivations.
• Technical Algorithm Interview: Two algorithmic exercises on CoderPad, similar to what you might find on LeetCode.
• React Coding Interview: A practical coding session on CoderPad, focused on React.
• Advanced Algorithm Interview: A single, more challenging algorithmic problem, again on CoderPad. Comparable to harder exercises on LeetCode.
• System Design Interview: Conducted on Excalidraw, this interview focused specifically on frontend architecture and design.
• Experience and Values Interview: A one-hour session split into two parts:
  • 30 minutes to discuss a project you’ve worked on, diving into the technical details.
  • 30 minutes of behavioral questions to assess your alignment with company values.

If you pass all these stages, the final step is the team match. You’ll have two interviews with different teams to learn about their work, ask questions, and ultimately decide which team you’d like to join.
