Most of the interview was about management style and dealing with situations and stakeholders. Some technical questions about DDoS, TCP, Kubernetes, VM vs Docker, gitops, release process and SRE practices. More like quick and effective checks to know if the candidate knows her/his stuff.

One of the most thought-provoking questions came during the technical round: “How would you design a self-healing system for a high-traffic payment infrastructure, and what metrics would signal true resilience?” It wasn’t just a design question—it was a test of mindset. I spoke about proactive anomaly detection using telemetry pipelines, a fallback architecture driven by service degradation levels, and the use of SLOs mapped to customer-facing impact metrics. But beyond the engineering, I emphasized my belief in building systems that carry empathy—for users, for developers, for the edge cases that often get ignored. That question stayed with me because it wasn’t just about code—it was about the philosophy behind reliability.
