The Problem

Your first coding interview shouldn’t bethe first time you think out loud.

LeetCode trains you to solve.Interviews test how you think.

What LeetCode trains

What interviews actually test

You solve in silence
You explain every decision out loud
No one asks why you chose that approach
They push back and you have to defend it
Pass or fail — no feedback
They watch how you handle being stuck
You memorize patterns
You adapt when the problem changes mid-way
The clock runs. You panic.
Composure is part of the score

The gap isn't your code. It's the silence between your thoughts. PrepCode closes that gap.
