Review 151 real DevOps interview questions from 2025 and 2026, organized by company
Do you have an interview next week and feel unsure about what to expect? This repository collects questions that people actually faced during DevOps, SRE, and cloud engineer interviews in 2025 and 2026. It does not rely on guesses like 'top 50 common questions'; instead, it stores the exact sentences heard at specific companies in individual files.
Records from actual interview sites
The repository contains 151 interview records. More than 85 company names are explicitly listed, while interviews where the company name was not disclosed are grouped separately in the Others/ folder. The content covers a wide range of topics, including Kubernetes, Docker, Terraform, AWS/Azure/GCP, CI/CD tools, Ansible, Linux scripting, and core SRE concepts such as SLI/SLO/SLA, observability, and incident response. Because questions vary depending on the candidate, round, and seniority level even at the same company, multiple interviews at a single company are kept in separate files rather than merged into one.
Company folders and file structure
Each company has its own folder, which contains markdown files detailing the interview experience. File names typically start with DevOps_Engineer.md, but if the candidate specified a particular role (e.g., SRE), the name includes the role, such as SRE_principal.md. If a second interview was conducted at the same company, a file with the suffix _2 is added. Interview records where the company name is unknown are stored in the Others/ folder, allowing users to understand general question flows without being limited to a specific company.
Preparation strategy and contribution methods
If you are applying to a specific company, opening that company's folder to review the questions directly is the fastest approach. If you want to prepare broadly without limiting yourself to one company, it is recommended to read folders from various companies, including product companies, service companies (e.g., TCS, Infosys, Wipro), and fintech firms. Comparing the scope and depth of questions provides more information than a single list. If you wish to share your own interview experience, you can add a new file to the relevant company folder. Including your role and years of experience at the top of the file helps other candidates determine how similar their situation is to yours.
Things to check before use
This repository is maintained using personal time, and new interview records are added regularly. However, not all records reflect the latest technology trends, as they represent the questions asked at the time of the candidate's interview, which may differ from current company policies or technology stacks. Additionally, interview styles at specific companies can vary by candidate, so while these records are useful for reference, you should prepare to respond flexibly in actual interviews. If you find the repository useful, clicking the star button helps the next candidate find it easily, which contributes to the project's sustainability.
