Daily DevOps Interview Questions Day #58

Daily Interview Questions for SRE and DevOps engineers

Question for the day:

We’re going to go through a production troubleshooting scenario today!! The goal of this exercise will be to see how you get to the root of a problem not necessarily solving it

Scenario

Your company runs a real-time ride-hailing platform (like Uber/Lyft). During peak hours, you see sporadic trip booking failures and increased latency in the booking-service API. You are the SRE on-call, and product has just reported 10% of users are seeing failures in the last 15 minutes.

Your task:

• Identify what could be causing the issue.

• Design a high-level architecture and mitigation plan to make the booking system resilient to sudden traffic surges and dependency slowness (e.g., payment service or maps API).

• Talk through SLOs, dashboards, and how you’d respond to this incident.
