Live Coding Prep

Why Live Coding Matters

Live coding isn't just about passing interviews. It's a way to test yourself honestly, without autocomplete, without AI assistants, and without the comfort of endless documentation tabs.

Of course, in real projects you'll use all those tools — and you should. But once in a while, stripping them away gives you a reality check:

• How well do you actually know the basics?
• Can you still write a loop, handle state, or build a small component from scratch?
• Do you stay calm and structured when no tool is holding your hand?

That's why live coding practice is valuable. It builds confidence not only for interviews but also for everyday work, because you know your skills stand on solid ground.

Step 1: Practice Without Autocomplete

Autocomplete is great for day-to-day work, but in interviews it can trip you up.
Set up your editor with autocomplete disabled, or use an online platform that forces you to type everything out.

Try solving short problems like:

• Reverse a string
• Find the first non-repeated character in a string
• Implement a debounce function
• Render a list in React with filtering and empty/error states

Mentioning frameworks here is important: you may be asked to build a small UI component in React, Vue, or Angular. Think of something like a modal, a dropdown, or a search bar with API integration. These are the kinds of tasks clients actually care about.

Step 2: Explain While You Code

Don't just type silently. In real interviews, silence feels like confusion.
Practice explaining your thought process out loud:

• “I'll start by splitting the string into an array…”
• “This looks like a case for map instead of forEach…”
• “If I had more time, I'd optimize this…”

This proves you're structured and able to communicate under pressure.

Step 3: Simulate Interview Conditions

Set a timer for 30-45 minutes. Pick a problem that fits in that time and commit to solving it like it's the real thing.
Don't pause, don't Google every detail — unless the real interview allows it.

For UI-related tasks, practice on platforms like Frontend Mentor or Codewell. For logic warmups, go with LeetCode Easy or Codewars. If you want pure CSS fluency, try CSSBattle.

Step 4: Review and Adjust

After each session, take notes:

• Did you freeze?
• Did you explain your thought process clearly?
• Was your code easy to follow?

Patterns matter. If you always get stuck on array methods, spend your next session reviewing them. If you ramble too much, practice explaining in shorter sentences.

Closing Reminder

Live coding is not about showing off. It's about showing that you can stay calm, solve problems, and communicate clearly.
The more you simulate the real conditions now — especially with frameworks like React, Vue, or Angular — the less stressful the actual interview will feel.
