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

How did you configure the CI/CD pipeline to ensure continuous deployment without any manual intervention?
- Expected Answer: The pipeline should be fully automated, triggering builds and deployments based on changes pushed to the repository.
- Sample Answer: "I used GitLab CI to set up a pipeline that is triggered whenever new code is pushed to the main branch. The pipeline includes stages for building, running automated tests, and deploying the app to AWS using Terraform for infrastructure as code."
Which tools did you choose for automating infrastructure, and why?
- Expected Answer: Candidates should choose a tool like Terraform, Ansible, or CloudFormation and explain how it helps automate infrastructure provisioning and scaling.
- Sample Answer: "I chose Terraform because it allows for modular and reusable infrastructure, and its support for multiple cloud providers makes it flexible for scaling the infrastructure as needed."
What steps did you take to ensure the application is scalable and can handle increased traffic?
- Expected Answer: Candidates should mention scaling mechanisms such as load balancers, auto-scaling groups, and monitoring tools.
- Sample Answer: "I deployed the application behind an AWS load balancer, with auto-scaling policies configured to increase instances based on CPU utilization. I also used CloudWatch for monitoring and alerting."

Behavioral questions

Duration : 10 minutes/question

How do you handle communication when different teams (development, operations, security) have conflicting priorities?
- Expected Answer: The candidate should emphasize open communication, collaboration, and finding common ground.
- Sample Answer: "I schedule regular meetings with all teams to ensure clear communication of priorities. I make sure each team understands the impact of their work on the overall project and encourage collaboration to resolve conflicts."
Tell us about a time when a deployment failed. How did you troubleshoot and resolve the issue?
- Expected Answer: The candidate should describe a systematic approach to troubleshooting, such as reviewing logs, identifying the root cause, and applying a fix.
- Sample Answer: "During a deployment, a service failed to start due to a missing environment variable. I checked the logs to pinpoint the issue, updated the CI/CD pipeline to ensure environment variables were correctly passed, and redeployed the service successfully."
How do you prioritize tasks when managing multiple projects and tight deadlines?
- Expected Answer: The candidate should describe prioritization techniques, such as focusing on high-impact tasks or using project management tools.
- Sample Answer: "I prioritize tasks based on their impact on the overall project timeline. I also use tools like Jira to track progress and ensure that high-priority items are addressed first while maintaining open communication with stakeholders."

Problem-Solving Skills	3	Took longer to identify issues in deployment.
Leadership	4	Demonstrated ability to manage cross-functional teams.
Cultural Fit	5	Aligned well with company values and teamwork.
Communication	4	Clear explanation of technical solutions.

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.
