What actually moves the needle
Preparation habits pulled from candidates who went through the process more than once.
Study the pattern, not the problem
Two Sum and Subarray Sum look different until you notice they're both solved with the same hash map trick.
Say your answer out loud
Silent practice hides the moments where your reasoning has a gap. Reading aloud finds them before the interview does.
Time-box every rep
Twenty-five minutes per question, no exceptions. Interviewers won't give you the extra ten either.
Revisit what you got wrong
A missed question you review twice sticks. One you skip past tends to show up again in a different interview.
