Make your reasoning visible in three passes: restate the task and constraints, explain a suitable approach, then code while narrating key decisions and the invariant you are maintaining. This routine can help an interviewer follow your work and catch misunderstandings early; it is a communication technique, not a proven way to guarantee a job offer.
Why narrate your reasoning?
Silent coding can leave an interviewer guessing whether you understand the problem, have chosen an intentional strategy, or are stuck. In a personal how-to article on DEV Community, author Timevolt describes freezing during a Two Sum whiteboard interview and realizing that the interviewer could not see the reasoning behind the code.
Thinking aloud gives the interviewer a view of how you arrived at a solution. It also gives you an early chance to surface a misunderstanding before it becomes a larger implementation problem. But narrating every keystroke can obscure the important decisions. Aim to explain what matters and why, not to provide a running commentary on syntax.
What’s actually slowing this PC down?

Use a three-pass routine
Timevolt describes the sequence this way: “Before you write a single line of code, you verbalize three things in this exact order:” The routine is easiest to apply when you treat understanding, planning, and implementation as distinct passes.

1. Restate the task and clarify constraints
Put the problem in your own words, then identify details that affect the solution. For Two Sum, for example, you might say: “Given an array of integers and a target, I need to return the indices of two distinct elements whose values add up to the target.”
Ask about any detail that is unclear and would change the implementation, such as whether there is guaranteed to be exactly one answer or whether the same array position could be used twice. Do not invent assumptions silently; state the assumption you plan to use if the prompt leaves a detail open.
2. Explain the approach before coding
Give a short plan and connect it to the problem’s requirements. For Two Sum, a one-pass hash map can store values already seen and their indices. For each current value, check whether the complement needed to reach the target is already stored. This avoids comparing every pair.
You do not need to lecture on every alternative. Explain enough for the interviewer to understand why the data structure fits and what you expect the algorithm to do. If you are unsure which approach is best, make the uncertainty explicit and compare the relevant trade-off before committing.
3. Code while narrating decisions and the invariant
As you implement, explain significant steps: “I’m checking for the complement before adding the current value, so I can’t pair this element with itself.” Then state the invariant you are preserving: before processing each element, the map contains values and indices from earlier elements only.
That kind of commentary makes the logic inspectable without reading every line aloud. Keep syntax details brief unless a language-specific choice affects correctness.
What to say when you hit a snag
Do not debug in silence, and do not fill the pause with guesses. Describe what you observe, what it may indicate, and what you will check next. For example: “This returns the same index twice in this case. That suggests I may be inserting the current value too early. I’ll check the order of the lookup and insertion.”

If you find the issue, explain the correction briefly; if you do not, make your next check clear rather than pretending certainty.
Best Value
Balance clarity with natural conversation
- Do: explain why you chose an approach and why a key implementation step is necessary.
- Do: pause after your plan so the interviewer can ask a question or point out a constraint.
- Do: state assumptions and narrate meaningful debugging checks.
- Avoid: jumping straight into code before confirming what the prompt means.
- Avoid: narrating every keystroke, repeating the same explanation, or leaning on filler words.
- Avoid: treating a proposed plan as final if a clarification changes the problem.
The goal is to talk through your reasoning clearly without sounding scripted. Use the routine as a mental checklist, not a speech to recite word for word.
Practice the routine before an interview
Timevolt suggests choosing a LeetCode medium problem, setting a 15-minute timer, and solving aloud with a friend, a rubber duck, or a phone recording. The timer is a practice constraint from the author, not a universal interview time limit.
- Choose a problem and start a recording or ask a practice partner to listen.
- Restate the task and constraints before proposing an approach.
- Explain why your approach fits, then implement it while describing important choices and the invariant.
- When you encounter a problem, say what you observed and what you will check next.
- Review the recording or ask for feedback: Did you restate the task? Did you justify the approach before coding? Did you explain the reasons behind key steps?
The same communication habit can be applied to graph traversal or a system-design sketch, according to Timevolt. The details differ, but the useful pattern is to make your interpretation, plan, and important decisions visible.
What this technique can—and cannot—show
Timevolt’s DEV Community article is a personal account, not a controlled study or an official hiring rubric. The author reports positive feedback and a better-feeling interview experience, but provides no sample size, comparison group, or quantified hiring result. The routine may make your reasoning easier to follow; the account does not establish that it improves hiring outcomes or guarantees a pass.
Use it to communicate your problem-solving process, not as a substitute for technical preparation. A clear explanation helps an interviewer understand what you are doing, but the quality and correctness of the solution still matter.
