• How would you implement service mesh capabilities and what benefits would you expect for observability and traffic control?
• Explain the strategies you would use to ensure data consistency across distributed stores in the cloud.
• Describe cost optimization techniques at scale including rightsizing, reserved instances, and architectural changes.
• How do you handle identity federation and single sign on across hybrid cloud and on prem systems?
• Discuss approaches to implementing platform engineering practices to enable self service infrastructure for developer teams.
• How would you design a secure and compliant cloud environment for regulated workloads including encryption, auditing, and policy enforcement?
• Explain how you would implement chaos engineering experiments and use results to improve system reliability.
• Describe a migration strategy for moving petabyte sized datasets to a cloud data lake with minimal business disruption.
• As a senior Cloud Engineer, how would you mentor junior engineers and influence cloud architecture decisions across teams?

Pre-Screening Video Interview Questions for Cloud Engineer

These prompts are ideal for one-way video interviews on ScreeningHive to quickly assess technical understanding, communication, and problem solving before live interviews.

1. Describe a recent cloud migration you worked on and your specific contribution

   This question evaluates practical experience, ownership, and the candidate ability to communicate technical work concisely.

2. Explain how you would secure an S3 or object storage bucket that contains sensitive data

   This assesses knowledge of access controls, encryption, and best practices for protecting cloud storage.

3. Walk through your process for diagnosing a production outage affecting a critical API

   This measures incident response skills, troubleshooting methodology, and ability to prioritize steps under pressure.

4. Provide a short overview of how you use Infrastructure as Code in your workflow and a tool you prefer

   This evaluates familiarity with IaC principles, tools like Terraform or CloudFormation, and automation practices.

5. Give an example of a cost reduction you implemented in a cloud environment and the impact it had

   This looks for practical cost optimization experience and the ability to quantify business value.
