For an EY Technology Consulting – Cloud Engineer interview, you'll typically be evaluated on four areas:
- Cloud
technical knowledge (Azure/AWS/GCP)
- Consulting
and problem-solving skills
- DevOps
& automation
- Behavioral
and communication skills
Here are 10 of the most common interview questions, along with sample answers and tips on how to answer effectively.
1. Tell me about yourself.
What the interviewer wants
A concise overview of your experience and why you're a fit
for EY.
Sample Answer
I have experience in cloud engineering with a strong focus
on designing, deploying, and supporting cloud infrastructure. I've worked with
cloud platforms such as Azure and AWS, infrastructure automation using
Terraform, CI/CD pipelines, and container technologies like Docker and
Kubernetes. In my current role, I collaborate with development and operations
teams to build secure, scalable, and reliable cloud solutions while
troubleshooting production issues and optimizing cloud costs. I'm excited about
EY because it combines technical innovation with consulting, allowing me to
solve business problems while working with global clients.

2. What cloud platform have you worked with?
Sample Answer
My primary experience is with Azure, where I've worked with
Virtual Machines, VNets, NSGs, Azure Storage, Azure Monitor, Key Vault, Azure
App Services, AKS, and Azure DevOps. I've also used AWS services including EC2,
S3, IAM, CloudWatch, RDS, and Lambda. I understand cloud architecture,
networking, security, and high availability across both platforms.
How to answer
Mention:
- Compute
- Storage
- Networking
- IAM
- Monitoring
- Security
3. Explain the difference between IaaS, PaaS, and SaaS.
Sample Answer
|
Model |
Description |
Example |
|
IaaS |
Infrastructure only |
Azure VM, AWS EC2 |
|
PaaS |
Platform managed by cloud provider |
Azure App Service |
|
SaaS |
Complete software |
Microsoft 365, Salesforce |
Example explanation:
IaaS gives maximum control over infrastructure, PaaS
abstracts infrastructure management so developers can focus on applications,
and SaaS delivers fully managed software accessible through a browser.
Interview Tip
Always give examples.
4. What is Infrastructure as Code (IaC)?
Sample Answer
Infrastructure as Code means provisioning cloud
infrastructure using code rather than manually creating resources. Tools like
Terraform, ARM templates, or AWS CloudFormation ensure consistency, version
control, repeatability, and faster deployments.
Example:
terraform apply
creates the complete environment automatically.
Mention Benefits
- Automation
- Version
control
- Repeatability
- Less
human error
5. Explain a CI/CD pipeline.
Sample Answer
CI/CD automates software build, testing, and deployment.
Typical flow:
Developer
↓
Git
↓
Build
↓
Unit Tests
↓
Docker Image
↓
Container Registry
↓
Deploy to Kubernetes
↓
Production
Common tools:
- Azure
DevOps
- GitHub
Actions
- Jenkins
- GitLab
CI
6. How do you secure cloud resources?
Sample Answer
Cloud security includes:
- IAM
with least privilege
- Multi-Factor
Authentication (MFA)
- Encryption
at rest and in transit
- Network
Security Groups (NSGs)
- Firewalls
- Key
Vault or Secrets Manager
- Private
Endpoints
- Logging
and monitoring
- Security
Center / Defender
Good Ending
Security should be incorporated from the design stage rather
than added after deployment.
7. Describe a cloud migration project.
Sample Answer
We migrated an on-premises application to Azure. We assessed
dependencies, designed the target architecture, created infrastructure using
Terraform, migrated databases with minimal downtime, configured monitoring and
backups, validated performance, and optimized costs after migration. The
migration improved scalability, reliability, and reduced operational overhead.
Interview Tip
Use the STAR format:
Situation
Task
Action
Result
8. How do you troubleshoot a cloud application that's
running slowly?
Sample Answer
I follow a structured approach:
- Check
application logs
- Review
monitoring dashboards
- Check
CPU and memory usage
- Review
network latency
- Check
database performance
- Verify
autoscaling
- Review
recent deployments
- Roll
back if necessary
Mention Tools
- Azure
Monitor
- CloudWatch
- Grafana
- Prometheus
- Application
Insights
9. Why do you want to join EY?
Sample Answer
EY offers the opportunity to work with global clients on
large-scale cloud transformation projects. I enjoy solving business problems
through technology, and EY's consulting environment will allow me to grow
technically while improving client engagement, communication, and leadership
skills. I also appreciate EY's focus on innovation, cloud modernization, and
continuous learning.

❌ Brand only
Focus on:
- Learning
- Consulting
- Global
projects
- Growth
10. Tell me about a difficult problem you solved.
Sample Answer
During a production deployment, a cloud application became
unavailable due to a misconfigured network security rule. I quickly identified
the issue through monitoring logs, restored service by correcting the
configuration, validated application health, documented the root cause, and
introduced an automated validation step into the deployment pipeline. This
reduced similar incidents in future deployments.
