Technical Interview Preparation
Technical interviews test fundamentals. Official documentation is the authoritative source for language behavior, framework concepts, and system design patterns. Review it anywhere with DocNative.
RTFM Before the Interview
Technical interviews test whether you actually understand the technologies you claim to know. Interviewers ask about edge cases, standard library functions, and framework behavior that is documented officially but often forgotten.
"What happens when you call sort() on a list of mixed types in Python?" The answer is in the documentation. So are the nuances of JavaScript's this binding, React's reconciliation algorithm, and Kubernetes pod scheduling.
Documentation beats blog posts for accuracy. When you reference official docs, you know the information is current and correct. That confidence shows in interviews.

Review official documentation—authoritative, current, and comprehensive
What to Review
Language Fundamentals
Review language fundamentals: data types, control flow, functions, classes. Interviewers test these basics even for senior roles. Python, JavaScript, or your interview language of choice.
Data Structures
Understand standard library data structures. Python collections, JavaScript array methods, Go slices and maps. Know what is built-in before reaching for external libraries.
Framework Concepts
For framework-specific roles, review core concepts. React hooks and component lifecycle. Django models and views. Know the framework philosophy, not just syntax.
System Design
System design interviews reference real infrastructure. Kubernetes concepts, AWS services, database fundamentals. Documentation provides accurate mental models.
When to Review
Interview prep is not just about grinding LeetCode. Understanding language and framework fundamentals helps you write cleaner solutions and explain your reasoning clearly.
The week before: Identify technologies mentioned in the job description. Download relevant documentation and read through fundamentals during commutes.
The day before: Review bookmarked sections on concepts you found tricky. Refresh your mental model of core patterns.
Before the interview: Quick scan of key sections while waiting. Having documentation offline means no WiFi hunting in office lobbies or relying on mobile signal.
