A Step-by-Step Guide to Solving Technical Interview Questions

Technical interviews really suck, don't they? They can feel like you're trying to solve a Rubik's Cube blindfolded while riding a roller coaster. But fear not - armed with a solid and structured game plan, you can navigate that wild jungle with some style and swagger. That's the goal with this post - to give you a problem solving framework that can be applied to a broad set of technical interview questions so you can show off your knowledge and skills even when you get stuck.

TRAIN OF THOUGHT

Subsets (Power Set)

Learn how to solve the Subsets coding problem to prepare for your next technical interview! The Subsets problem tests whether you understand how to explore a decision tree without missing cases or duplicating work. It's a classic interview question because the same thinking shows up across backtracking, bit manipulation, and combinatorics problems.

Permutations

Learn how to solve the Permutations coding problem to prepare for your next technical interview! Interviewers use it to see whether you can reason about recursion, backtracking, and state management, and whether you can do it without losing track of where you are.

Word Break

Learn how to solve the Word Break coding problem to prepare for your next technical interview! Interviewers love Word Break because it exposes whether you can translate a vague problem statement into a clean DP state definition. The algorithm itself isn't complicated. The hard part is seeing the problem the right way.

Unique Paths II

Learn how to solve the Unique Paths II coding problem to prepare for your next technical interview! Unique Paths II looks almost identical to Unique Paths. One small change: obstacles. That single twist forces you to slow down, re-examine every assumption, and adapt the same DP pattern carefully. Interviewers love this problem precisely because it separates candidates who understand the pattern from those who just memorized it.

Unique Paths

Learn how to solve the Unique Paths coding problem to prepare for your next technical interview! Unique Paths tests whether you can recognize a counting dynamic programming pattern and model state correctly. It's a classic interview question because the logic scales cleanly to harder grid problems. Once you've internalized the thinking here, a whole family of harder problems opens up.

I hate interviewing. Technical interviews are especially annoying. So I created this blog to practice for technical interviews. Hopefully it's helpful to you, too!
