Technical Interview Study Guide

Use this worksheet to track problems you've solved, patterns you've learned, and mistakes to avoid.

How to Use

For each problem you work on, fill out the sections below. Review your notes before interviews.

Problem Template

Problem Name

[Problem title and link]

Category/Pattern

What type of problem is this? (e.g., binary search, dynamic programming, graph traversal, string manipulation)

Problem Statement

[Paraphrase the problem in your own words]

Key Clues

• What data structure hints are in the problem?
• What constraints matter? (time, space, edge cases)
• What do similar problems have in common?

Approach (Pseudocode)

[Write the algorithm in plain English before coding]

Time Complexity

[Best, average, worst case]

Space Complexity

[Include auxiliary space]

Mistakes I Made

• First attempt: [what went wrong]
• Fix: [how you corrected it]

Confidence Level

[ ] Can solve from scratch [ ] Can solve with hints [ ] Need to review again
