Start with a goal, not a question list
Lists with hundreds of questions create a sense of progress but rarely clarify priorities. Preparing for a general Senior Backend interview and a specific Node.js position requires different depth, even when the technology lists look similar.
Define the role, seniority, primary stack, and deadline. If you have a job description, identify the required skills and technologies mentioned repeatedly. Use them as a filter for everything else.
Build a topic map
Divide your preparation into topics and give each one an importance and target depth. Do not try to reach expert level in everything. A role may only require Kubernetes fundamentals while expecting you to explain the Event Loop, transactions, and caching trade-offs in detail.
- Fundamentals: terminology and core concepts.
- Practical: application in real projects.
- Advanced: production scenarios and trade-offs.
- Expert: internals and diagnostics.
Practice formulating the answer
Reading a correct answer is easier than reproducing it without hints. Answer out loud first, or briefly write down your reasoning. Only then compare your response with the key points.
Assess yourself honestly: “I don't know,” “partially,” or “confident.” This assessment is more useful than an abstract progress percentage because it determines when the question should return.
Plan a specific session for today
Your daily plan should fit the time available and combine new cards with reviews. Twenty focused questions are more useful than an endless queue you can never finish.
Structured preparation follows a short cycle: attempt an answer, assess yourself, close the gap, and review later. Mentaro turns this cycle into a personalized program.
