  • Round 2 (System Design, 60 minutes): Design a scalable system for a financial application (e.g., payment processing).
  • Round 3 (Technical Deep Dive & Culture Fit, 90 minutes): In-depth coding review of a personal project and behavioral questions.
  • Round 4 (Optional, for Exceptional Candidates): Meeting with an Engineering Lead for strategic technical discussions.

How Long Does It Take to Receive an Offer After the Final Interview?
