• Technical Deep Dive (60-90 min)
• Deep dive into past work, including architecture decisions, trade-offs, scaling challenges, failures, and API/data model design.
• On-site Interviews (2-3 hours max)
• Includes conversations with leadership and peers, a practical engineering exercise (debugging, small build task, or architecture walkthrough), and a focus on collaboration style, communication, and cultural fit.

• We care about outcomes: Homeownership rates in Germany are far below the European average. We're here to enable wealth creation for everyone.
