The Raylo Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
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 Raylo interview outcomes, avoid these common traps:
- Describing a situation where they were simply doing their job.
- Not explaining the impact or learning from the experience.
- Suggesting vertical scaling as the primary solution without considering horizontal scaling.
- Not considering the impact of the fix on other parts of the system.
