Interview Process

• Screening intro (30 min, video call)

• Tech challenge (3-4 hours)
  • An open project, on your time, due within 5 days. No leetcode disconnected from the actual work. We evaluate your code under real conditions: prompt reading, architecture choices, tests, readability.
• System design (1 hour video call)
  • You walk us through an architecture you know in depth (a recent project, or an in-house topic). We dig into trade-offs, constraints, pivots. We want to see your depth on a domain you master — not test your cramming.
• Culture fit (45 min, in-person or video call)
  • With a founder (Sébastien or Vianney). We validate alignment: ownership, quality, client relationship, potential international mobility via Mobbeal. Your moment to ask all the hard questions.
• References + offer (5-7 days)
  • Currently based in Japan with valid work authorization — no relocation or visa sponsorship from overseas for this role
  • Two technical references called (with your consent). If everything fits, a detailed offer is sent — full package, Mobbeal mobility conditions if applicable, onboarding plan. You have 7 days to decide.

Note: Work contract via Abbeal.
