Technical interviews can feel like a roulette wheel—until you build a repeatable system for solving problems under pressure. Instead of chasing hundreds of random questions, focus on a small set of skills you can apply to almost anything.
Before you code, force clarity:
n <= 10^5 → likely O(n log n) or O(n)).This prevents the most common failure: solving the wrong problem confidently.
Most interview problems are variations of a few core patterns. Build a mental menu:
When you see a new question, ask: What pattern is this closest to? Even if you’re unsure, proposing a candidate pattern signals strong problem-solving.
Interviewers grade your thinking. Try this talk track:
Tip: Say the invariants out loud, e.g., “My window always contains at most k distinct characters.”
Small habits reduce bugs dramatically:
left, right, freq, seen)After practice, write:
That’s where real improvement happens.
If you had to pick one area to improve for your next technical interview—pattern recognition, communication, or debugging under pressure—which would it be, and what’s been hardest about it?
Love this framing—“repeatable system” is exactly what reduces the roulette-wheel feeling. One extra layer I’ve seen help candidates: make your system ...
