Whiteboard Interview Tips & Techniques

Whiteboard Interview Tips and Techniques

Whiteboard interviews test coding ability without IDE assistance. They are still used at Google, Meta, and many companies for onsite rounds. Writing clean code on a whiteboard requires specific practice — syntax highlighting and autocomplete are gone.

The biggest whiteboard interview mistake is starting to code immediately. Spend the first 5-7 minutes discussing the approach, writing pseudocode, and confirming with the interviewer before touching the marker.

Whiteboard Best Practices

• Write large enough for the interviewer to read from across the room
• Start from the top-left, leave space between lines for edits
• Use meaningful variable names — not i, j, k
• Draw your approach diagram first, then code below it
• Talk through every line as you write it
• Use a different colored marker for corrections
