Application Review (within 2 weeks) - we look at your code and contributions 2. Initial Chat (30 min) - casual conversation about your experience and our work 3. Technical Interview (2 - 3h) 1. Technical Deep-Dive - discuss kernel architecture, past debugging challenges and how you approach problem-solving (no whiteboard coding) 2. Code Review Session - review real patches together, discuss trade-offs 3. Client Scenario Discussion - talk through a realistic customer situation: balancing technical debt, timeline pressure and upstream goals (we want to see your thought process, not a "right answer") 4. Chief Operating Officer  (60 min) - meet the Chief Operating Officer, ask about day-to-day work and how Collabora works, discuss compensation and benefits. 5. Offer (within 1 week of final interview) Total timeline: 3-4 weeks from application to offer We provide feedback at every stage, and you'll always know where you stand. COLLABORA'S COMMITMENT We're committed to building a diverse team and inclusive environment. We encourage applications from people underrepresented in tech. We evaluate candidates based on skills and contributions, not pedigree. If you're unsure whether you qualify, apply anyway - imposter syndrome is real and you might be exactly who we're looking for.
