Technical questions

Recruitment Bullet

Duration : 10 minutes/question

  • Question: How did you configure the CI/CD pipeline for your application?
    • Expected Answer: The candidate should explain the process of setting up continuous integration and deployment using Jenkins, GitHub Actions, or another CI/CD tool, including any challenges they faced.
    • Sample Answer: "I used Jenkins for CI/CD. First, I created a Jenkinsfile to define the build and deployment pipeline. I configured stages for code testing, building Docker images, and deploying to an AWS EC2 instance using Ansible."
  • Question: What steps did you take to ensure the security of your application and cloud infrastructure?
    • Expected Answer: The candidate should mention practices like configuring IAM roles, applying SSL certificates, and setting up firewalls or security groups.
    • Sample Answer: "I ensured that only specific IAM roles had access to the EC2 instance and restricted the S3 bucket access to the app's VPC. Additionally, I added SSL certificates to secure the communication between the client and server."
  • Question: Can you explain the benefits of containerization and how Kubernetes helped in deploying your application?
    • Expected Answer: The candidate should explain containerization benefits such as consistency across environments and Kubernetes’ role in orchestrating multiple containers.‍
    • Sample Answer: "By containerizing the app using Docker, I ensured that it ran the same across different environments. Kubernetes helped me scale the application by managing multiple containers and providing load balancing."

Behavioral questions

Recruitment Bullet

Duration : 10 minutes/question

  • Question: Can you describe a time during the project when you faced an unexpected challenge? How did you handle it?
    • Expected Answer: The candidate should provide an example of a challenge, how they analyzed it, and the solution they applied.
    • Sample Answer: "During deployment, the CI/CD pipeline failed due to a missing dependency. I quickly debugged the issue, updated the pipeline to include the missing package, and redeployed successfully."
  • Question: How did you collaborate with others, if at all, while working on this task?
    • Expected Answer: The candidate should discuss their teamwork or communication methods during collaboration, even if it’s remote.
    • Sample Answer: "I worked with a colleague remotely for feedback on the CI/CD pipeline. We used Slack and shared code via GitHub, regularly updating each other on progress."
  • Question: How do you prioritize security and performance when developing cloud-based applications
    • Expected Answer: The candidate should demonstrate their ability to balance security requirements with performance optimization.‍
    • Sample Answer: "Security is always a top priority. I made sure to implement SSL certificates and restrict access with IAM roles, but I also used AWS CloudWatch to monitor performance and optimize resource usage."
