How to Pass the Zego Software Engineer Interview in 2026
The Zego DNA (TL;DR)
Zego's interview process centers on the user journey for gig workers using partners like Uber Eats. They test for a deep understanding of the trade-offs in simplifying complex products like 'Van Insurance' while maintaining regulatory compliance and user trust.
The Zego Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2

Round 4
Onsite CodingLeetCode-hard, debugging, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Zego interview outcomes, avoid these common traps:
- Incorrectly handling negative transaction amounts.
- Brute-forcing by checking every single timestamp.
- Using a naive approach that iterates through all events for each query.
- Underestimating the scale of data and the need for distributed processing.
