Work sample test (Home assignment)

Recruitment Bullet

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

  • Title: Design and Implement a CI/CD Pipeline
  • Objective: Evaluate the candidate’s ability to design, implement, and optimize a continuous integration and continuous deployment (CI/CD) pipeline using a cloud platform.
  • Requirements:
    • Design a CI/CD pipeline that automates the build, test, and deployment of a simple application to a cloud environment (e.g., AWS, Azure, or Google Cloud).
    • Use DevOps tools such as Jenkins, Git, Docker, and Terraform.
    • Implement automated testing as part of the pipeline.
    • Document the steps taken, tools used, and any challenges faced.
    • Provide suggestions for further optimization of the pipeline.
  • Time Frame: 3-5 days

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

Technical questions

Recruitment Bullet

Duration : 10 minutes/question

  • Question: How did you approach the design of the CI/CD pipeline in the work sample task? What were your key considerations?
    • Expected Answer: The candidate should explain their design approach, including considerations for scalability, security, and efficiency.
    • Sample Answer: "I designed the pipeline with scalability in mind, using Jenkins for automation and Docker for containerization. I also incorporated automated testing and security checks at various stages to ensure the pipeline is both robust and secure."
  • Question: What challenges did you encounter during the implementation of the CI/CD pipeline, and how did you overcome them?
    • Expected Answer: The candidate should identify specific challenges, such as integration issues or performance bottlenecks, and explain how they resolved them.
    • Sample Answer: "One challenge was integrating the testing suite with the CI/CD pipeline. I resolved it by using Docker to create a consistent testing environment and added a step in the pipeline to trigger tests automatically after each build."
  • Question: How would you optimize the CI/CD pipeline further to improve performance and reduce deployment time?
    • Expected Answer: The candidate should suggest practical optimizations, such as parallelizing tasks, caching dependencies, or using more efficient tools.
    • Sample Answer: "I would optimize the pipeline by parallelizing the build and test processes, using caching for dependencies, and exploring the use of a more lightweight containerization tool to reduce build times."

Behavioral questions

Recruitment Bullet

Duration : 10 minutes/question

  • Question: Describe a time when you had to lead a cross-functional team to implement a DevOps solution. How did you ensure successful collaboration?
    • Expected Answer: The candidate should explain their leadership and communication strategies, emphasizing collaboration and conflict resolution.
    • Sample Answer: "In my previous role, I led a team of developers, operations staff, and QA engineers to implement a new CI/CD pipeline. I ensured clear communication by setting up regular meetings, using collaboration tools like Slack, and addressing any conflicts early to keep the project on track."
  • Question: How do you handle situations where there is resistance to adopting DevOps practices or tools?
    • Expected Answer: The candidate should demonstrate their ability to manage change, including how they communicate the benefits of DevOps and address concerns.
    • Sample Answer: "I approach resistance by first understanding the concerns of the team members. I then provide training sessions and demonstrate the long-term benefits of DevOps practices, such as improved efficiency and reduced downtime, to gain their buy-in."
  • Question: Can you give an example of a time when you had to make a difficult decision related to a DevOps project? How did you handle it?
    • Expected Answer: The candidate should provide a specific example, including the decision-making process and the outcome.
    • Sample Answer: "During a critical deployment, I had to decide whether to proceed with a new tool that hadn’t been fully tested or delay the deployment. I chose to delay the deployment, communicated the reasons to stakeholders, and ensured thorough testing before proceeding. This decision ultimately prevented potential issues in production."
