Technical questions

Recruitment Bullet

Duration : 10 minutes/question

  • Question: Describe the architecture you designed for the work sample task. Why did you choose the specific AWS services?
    • Expected Answer: The candidate should explain the architecture, including the use of EC2 for compute, S3 for storage, RDS for databases, and any other relevant services. They should discuss scalability, security, and cost-effectiveness.
    • Sample Answer: "I chose EC2 instances for compute because they provide the flexibility to scale based on traffic. S3 was used for static content storage due to its durability and cost-effectiveness. I also included RDS for database management to ensure data consistency and reliability. The architecture is designed to be highly available by using multiple availability zones."
  • Question: How did you implement Infrastructure as Code (IaC) in the task, and what challenges did you face?
    • Expected Answer: The candidate should describe the tools used (e.g., CloudFormation, Terraform), the IaC structure, and any challenges related to configuration management, dependencies, or resource conflicts.
    • Sample Answer: "I used Terraform to implement IaC because of its support for multi-cloud environments and modularity. A challenge I faced was managing dependencies between resources, which I addressed by defining explicit dependencies in the Terraform configuration. This ensured that resources were created in the correct order."
  • Question: What considerations did you make for security in your AWS architecture?
    • Expected Answer: The candidate should discuss security best practices such as using IAM roles, encrypting data at rest and in transit, setting up security groups, and implementing VPCs for network isolation.
    • Sample Answer: "Security was a top priority, so I implemented IAM roles with the principle of least privilege to control access. I also used SSL for data in transit and encrypted all data stored in S3 and RDS. The application is hosted within a VPC, with security groups configured to restrict access to specific IP ranges."

Behavioral questions

Recruitment Bullet

Duration : 10 minutes/question

  • Question: Describe a time when you had to troubleshoot a complex issue in a cloud environment. How did you approach the problem?
    • Expected Answer: The candidate should describe the situation, the steps they took to identify and resolve the issue, and the outcome.
    • Sample Answer: "In my previous role, we encountered a performance issue with our AWS-hosted application during peak traffic. I started by analyzing CloudWatch logs to identify the bottleneck, which was related to database connection limits. I implemented a solution by increasing the RDS instance size and optimizing the connection pooling strategy, which resolved the issue."
  • Question: How do you handle situations where you need to learn a new technology or tool quickly to complete a project?
    • Expected Answer: The candidate should explain their approach to learning new tools, including researching, experimenting, and seeking help when needed.
    • Sample Answer: "When faced with learning a new tool, I first research the official documentation and online resources to understand the basics. I then create a small test project to get hands-on experience. If I encounter any roadblocks, I reach out to colleagues or online communities for support. This approach helps me quickly get up to speed and apply the new knowledge effectively."
  • Question: Can you give an example of how you have contributed to improving a process or workflow in your previous roles?
    • Expected Answer: The candidate should provide a specific example, including the process or workflow, the changes they implemented, and the impact on the team or project.
    • Sample Answer: "In my last position, I noticed that our manual deployment process was time-consuming and prone to errors. I introduced a CI/CD pipeline using Jenkins and AWS CodeDeploy, which automated the build and deployment process. This reduced deployment times by 50% and significantly decreased the number of errors, improving overall efficiency."
