I would combine proactive monitoring and alerting with geo-redundancy, capacity planning, tested failover procedures, disciplined change control, and blameless post-incident reviews that result in tracked corrective actions. Describe your approach to accepting a new core network capability into a Run team. I would establish explicit operational-readiness criteria covering architecture documentation, monitoring, alerting, runbooks, access controls, backup and recovery, performance testing, failover testing, support escalation paths, and team training. The service would be accepted only after evidence confirms that these controls work in production-like conditions and the operating team can support it safely. How have you led teams working across engineering, QA, and reliability disciplines? I align teams around clear service outcomes, ownership boundaries, delivery priorities, and shared quality standards. I use regular one-to-ones, capacity planning, transparent performance feedback, and retrospectives to support growth while ensuring that engineering, QA, and SRE work is coordinated rather than siloed. What controls would you implement to prevent configuration drift across CNFs, VNFs, and environments? I would treat configuration as version-controlled code, require peer-reviewed changes, automate deployment and rollback, and continuously compare deployed states against approved baselines. Drift alerts, auditable change records, environment promotion rules, and periodic recovery tests would provide additional control. How would you troubleshoot a decline in mobile data session success rates after a partner integration change? I would first assess the scope by segmenting the affected traffic by market, partner, subscriber profile, APN, and network element. I would correlate signalling traces and platform metrics across HSS/HLR, policy, packet core, Diameter, DNS, and GTP, compare the change against known-good baselines, mitigate through rollback or traffic controls where needed, and lead a documented root-cause review with the partner.
