Selection Process

Interview Process & How to Prepare

  1. Screening Interview (with Hiring Manager) Focus: culture fit, background, and your motivation. Be ready to walk through your CV and ask questions about the company.
  2. Panel Interview (mixed US/RO panel, evening slot 17:00-18:00 start, ~2 hours)
  • Hour 1: Behavioral round covering conflict resolution and ownership of responsibilities. Prepare concrete examples from your own experience (STAR format works well).
  • Hour 2: Technical round. You'll receive a home assignment beforehand (a pull request to review) and be asked to walk through your code review live with the panel.

Good to Know

Come with real examples, not hypotheticals. For the technical round, focus on the quality and clarity of your review comments, not just finding bugs.
