Cloud network engineering interviews at tech giants require specialized knowledge beyond traditional networking – particularly when it comes to cloud-native services. In this final installment of our interview preparation series with Kam Agahian, we explore the specialized networking services that frequently appear in technical assessments.
Security takes center stage as we discuss the critical boundary between networking and security responsibilities. Kam explains that while routing traffic to firewalls falls squarely on the network engineer, security policies and posture typically belong to dedicated security teams at larger organizations. We compare traditional VM-based third-party firewalls with cloud-native security services, highlighting the architectural considerations for each approach.
DNS architectures represent another technical area where candidates must demonstrate proficiency. Beyond understanding traditional name resolution, you'll need familiarity with the hybrid cloud architectures that enable communication between on-premises and cloud environments. Kam singles out DNSSEC as deserving special attention during your preparation.
The landscape of multi-cloud connectivity has evolved dramatically, moving beyond simple cross-cloud connections to sophisticated integration patterns. Candidates who demonstrate awareness of recent developments – like Oracle's strategy of placing databases directly in other providers' data centers – stand out in interviews by showing they stay current with industry trends.
Throughout our conversation, we emphasize research as a critical interview preparation strategy. Review all cloud-related job postings at your target company to understand their technology ecosystem and identify potential multi-cloud scenarios. This contextual knowledge allows you to tailor your responses to the specific environment you'll potentially be working in.
