Tell me about your experience with DevOps.

DevOps is a highly technical field, requiring extensive knowledge of programming languages, cloud architecture, full-stack engineering, automation, and problem-solving. A computer science background is extremely helpful, though formal education isn’t strictly necessary and having comprehensive development and programming experience is equally valuable.

How will you approach a project that needs to implement DevOps?

The following standard approaches can be used to implement DevOps in a specific project:

Stage 1: An assessment of the existing process and implementation for about two to three weeks to identify areas of improvement so that the team can create a road map for the implementation.

Stage 2: Create a proof of concept (PoC). Once it is accepted and approved, the team can start on the actual implementation and roll-out of the project plan.

Stage 3: The project is now ready for implementing DevOps by using version control/integration/testing/deployment/delivery and monitoring followed step by step.

By following the proper steps for version control, integration, testing, deployment, delivery, and monitoring, the project is now ready for DevOps implementation.

How do you explain a complex DevOps process or strategy to someone who doesn’t have a technical background?

DevOps engineers frequently have to liaise with executives and other employees at the company to provide updates on ongoing projects. This requires them to distill technical information in a way that’s accessible to people from a wide range of background, so it’s important to get a sense of their communication style and interpersonal skills. Interviewers here look for, whether the candidate is able to convey information in a way that ensures key concepts are understood. A great answer will demonstrate strong verbal communication skills, as well as patience when sharing technical information with others.

This question helps the interviewer identify genuine passion for the field, and also provides deeper insights into the candidate’s background and interests. Interviewers look for signs that the candidate is deeply invested in growing their skills and advancing in the field.
