Tools, Frameworks & Implementation Proficiency Topics
Practical proficiency with industry-standard tools and frameworks including project management (Jira, Azure DevOps), productivity tools (Excel, spreadsheet analysis), development tools and environments, and framework setup. Focuses on hands-on tool expertise, configuration, best practices, and optimization rather than conceptual knowledge. Complements technical categories by addressing implementation tooling.
Infrastructure as Code Tool Proficiency (Terraform/CloudFormation/Ansible)
Deep proficiency in at least one IaC tool. For Terraform: understand resources, data sources, variables, outputs, local values, modules, state management, state locking, backend configuration (S3, Terraform Cloud), and best practices (remote state, sensitive variables, module organization). For CloudFormation: understand templates (YAML/JSON), stacks, parameters, conditions, mappings, resources, outputs, and intrinsic functions. For Ansible: understand playbooks, roles, inventory, variables, handlers, and idempotency. Write reusable, maintainable code: modules for Terraform, roles for Ansible. Understand code organization, naming conventions, and team collaboration practices.
Relevant Technical Experience and Projects
Describe the hands on technical work and projects that directly relate to the role. Cover specific tools and platforms you used, such as forensic analysis tools, operating systems, networking and mobile analysis utilities, analytics and database tools, and embedded systems or microcontroller development work. For each item explain your role, the scope and scale of the work, key technical decisions, measurable outcomes or improvements, and what you learned. Include relevant certifications and training when they reinforced your technical skills. Also discuss any process improvements you drove, cross functional collaboration required, and how the project experience demonstrates readiness for the role.
Command Line Proficiency and Troubleshooting
Comfortable using shell commands for system troubleshooting and administration. Key tools: ps (process information), top and htop (real-time monitoring), grep, sed, awk (text processing), curl (HTTP requests), netstat and ss (network statistics), du and df (disk usage), kill and killall (process termination), tar and gzip (compression). Know how to redirect I/O, pipe commands together, and create simple scripts. Understand how to use man pages.
Technical Skills and Tools
A concise but comprehensive presentation of a candidate's core technical competencies, tool familiarity, and practical proficiency. Topics to cover include programming languages and skill levels, frameworks and libraries, development tools and debuggers, relational and non relational databases, cloud platforms, containerization and orchestration, continuous integration and continuous deployment practices, business intelligence and analytics tools, data analysis libraries and machine learning toolkits, embedded systems and microcontroller experience, and any domain specific tooling. Candidates should communicate both breadth and depth: identify primary strengths, describe representative tasks they can perform independently, and call out areas of emerging competence. Provide brief concrete examples of projects or analyses where specific tools and technologies were applied and quantify outcomes or impact when possible, while avoiding long project storytelling. Prepare a two to three minute verbal summary that links skills and tools to concrete outcomes, and be ready for follow up probes about technical decisions, trade offs, and how tools were used to deliver results.
Team Specific Technical Stack and Backend Systems
Discuss the team's specific technologies mentioned in the job description (Node.js, Python, Java, PostgreSQL, MongoDB, AWS, Azure, etc.). Ask about their backend architecture, how they handle scalability and reliability, deployment practices, and monitoring/alerting. Inquire about recent technical decisions or challenges they've faced. Show interest in learning their specific tech stack and systems. Ask realistic questions about the ramp-up period and learning curve.
Specific Experience with Core DevOps Tools
Be prepared to discuss hands-on experience with specific tools relevant to the job description: CI/CD platforms (Jenkins, GitLab CI, GitHub Actions), containerization (Docker), orchestration (Kubernetes basics), cloud platforms (AWS, Azure, GCP), and Infrastructure as Code (Terraform, CloudFormation). Prepare concrete examples of how you used these tools.
Containerization Fundamentals
Foundational knowledge of container technology, focused on Docker and container workflows. Topics include what containers are and how they differ from virtual machines, container images and registries, building and reading Dockerfiles, running containers, volume and file system mounting, basic container networking, image layering and size optimization, and common use cases such as reproducible deployments for machine learning and microservices. Candidates should be able to explain the container lifecycle, why containerization matters in DevOps, and demonstrate simple hands on tasks like writing a basic Dockerfile and running containers locally.
Command Line and Shell Scripting
Practical skills using command line interfaces and writing simple shell scripts for automation and system administration across operating systems. For Linux this includes navigation and file operations, file permissions, process and service inspection, log viewing, package and systemctl management, common text processing and search utilities such as grep, find, sed, and awk, piping and redirection, environment variables, command substitution, and interactive use of editors and remote access tools. Shell scripting fundamentals include variables, conditionals, loops, functions, argument handling, basic debugging, and using bash to automate repetitive tasks. The scope also covers essential Windows command line and shell basics where relevant, including interactive commands, simple PowerShell cmdlets for process and service management, file and permission commands, and differences in syntax and environment when performing equivalent administrative tasks on Windows. Candidates may be evaluated on writing short scripts, composing command pipelines to accomplish tasks, and explaining tradeoffs between interactive commands and scripted automation.
Technology Stack Knowledge
Assess a candidate's practical and conceptual understanding of technology stacks, including major programming languages, application frameworks, databases, infrastructure, and supporting tools. Candidates should be able to explain common use cases and trade offs for languages such as Python, Java, Go, Rust, C plus plus, and JavaScript, including differences between compiled and interpreted languages, static and dynamic type systems, and performance characteristics. They should discuss application frameworks and libraries for frontend and backend development, common web stacks, service architectures such as monoliths and microservices, and application programming interfaces. Evaluate understanding of data storage options and trade offs between relational and non relational databases and the role of structured query language. Candidates should be familiar with cloud platforms such as Amazon Web Services, Google Cloud Platform, and Microsoft Azure, infrastructure components including containerization and orchestration tools such as Docker and Kubernetes, and development workflows including version control, continuous integration and continuous delivery pipelines, testing frameworks, automation, and infrastructure as code. Assess operational concerns such as logging, monitoring and observability, deployment strategies, scalability, reliability, fault tolerance, security considerations, and common failure modes and mitigations. Interviewers may probe both awareness of specific tools and the candidate's depth of hands on experience, ability to justify technology choices by evaluating trade offs, constraints, and risk, and willingness and ability to learn and evaluate new technologies rather than claiming mastery of everything.
