How to structure the interview to assess skills and cultural fit for {role_name}

Work sample test (Home assignment)

Assess the candidate’s practical skills by assigning a real-world task similar to the work they would do if hired.

Title: Develop and Deploy a Cloud-Native Application
Objective: The candidate must demonstrate their ability to build and deploy a cloud-native application on a cloud platform (AWS, Azure, or Google Cloud).
Requirements:
- Develop a simple web application (e.g., a task management app) using any programming language or framework.
- Set up the necessary infrastructure on a cloud platform (EC2, S3, RDS, or equivalent services).
- Deploy the application using a CI/CD pipeline (preferably Jenkins or GitHub Actions).
- Use Docker for containerization and deploy the app in a Kubernetes cluster.
- Implement security best practices, including IAM roles, VPC, and SSL certificates.
Time Frame: 3-5 days

Questions based on home assignment :

Once done with work sample test evaluate the candidate’s technical proficiency based on the work sample task.

Technical questions

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

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."

How to evaluate and compare candidates after interviews?

After interviews, it's important to evaluate and compare candidates based on a set of predefined criteria.Use scorecard to evaluate each candidate.

Sample scorecard based on pre-defined criteria. Here’s an example:

Criteria	Description	Rating (1-5)
Cloud Platform Knowledge	Demonstrates proficiency in AWS, Azure, or GCP.	[ ]
CI/CD & DevOps Practices	Familiarity with setting up pipelines and DevOps.	[ ]
Security Best Practices	Knowledge of cloud security and IAM configurations.	[ ]
Problem-Solving Ability	Ability to handle challenges effectively.	[ ]
Cultural Fit	Alignment with company values and team collaboration.	[ ]
Communication Skills	Clarity in explaining technical concepts.	[ ]

What criteria should be used to make the final hiring decision?

Final decisions should be based on the candidate's overall evaluation score, with a focus on important qualifications. Prioritize technical skills above everything else for a {role_name}, but do not forget about communication and cultural fit.
