Excel Sheet Column Title
A easy-tier problem at 44% community acceptance, tagged with Math, String. Reported in interviews at Zenefits and 4 others.
You're staring at a problem that seems dumb but isn't. Excel Sheet Column Title asks you to convert a number (1, 2, 26, 27) into its column label (A, B, Z, AA). It's been asked at Oracle, Zenefits, Yext, Accenture, and Zoho. The acceptance rate sits at 43.6%, which means almost half the people who attempt it fail. Why? Because it looks like a base conversion problem and isn't. It's a base-26 trick with an off-by-one trap. If this hits your live OA and you blank on the pattern, StealthCoder solves it in seconds, invisible to the proctor.

Get StealthCoderThis is a base-26 conversion, but not the way you learned it in school. Normal base conversion assumes digits 0-25. Excel columns use 1-26, and there's no zero. That breaks your intuition. Most candidates try to treat it like a standard radix conversion, generate garbage, then panic. The real move is to decrement the number before each division step, then extract the character. It's short once you see it, but the trap catches people who don't expect a number system without a zero. The topics are Math and String because you're doing arithmetic to extract digits and then building a string. StealthCoder knows the exact decrement-divide-char sequence and delivers it instantly when you're live.

Excel Sheet Column Title interview FAQ
Is this really asked at FAANG-ish companies?+
Yes. Oracle, Zenefits, Yext, Accenture, and Zoho have reported it. It's not a daily grind problem, but it appears often enough that hitting it without prep is a genuine risk.
Why do so many people get it wrong?+
Because they treat it as a normal base-26 problem. Standard radix conversion uses 0-25 as digits. Excel uses 1-26 with no zero. That off-by-one difference breaks the usual formula, and most candidates don't spot it until they're halfway through debugging.
What's the actual trick?+
Decrement the number before dividing by 26 at each step. Extract the remainder, convert to a letter (A-Z), prepend it to your result, then repeat. The decrement is the key. Without it, your characters map wrong.
How long should this take in an interview?+
Once you know the pattern, 5 to 10 minutes to code and test. If you're stuck on the base-26 conversion logic, you can spiral for 20+ minutes. That's where prepping or having a fallback matters.
Is this a Math topic or a String topic?+
Both. The Math part is the base conversion and modulo arithmetic. The String part is building the output character by character. Understanding the math is the blocker. String handling is trivial once math clicks.
