The “coffee cup test”: a surprising interview trick you need to know

Imagine this: you’re sitting in a job interview, nerves steadying, when the recruiter offers you a cup of coffee. Seems like a kind gesture, right? But what if that simple drink wasn’t about hospitality at all, but a quiet test of your attitude, initiative and ability to fit in? Welcome to the world of the “coffee cup test.”

A test hiding in plain sight

The idea behind this unusual recruitment tactic comes from Australian business leader Trent Innes, who used it while heading Xero Australia. The principle is deceptively simple: once the interview ends, the recruiter pays attention to what the candidate does with their empty cup.

Carry it back to the kitchen or ask where to put it, and you’ll score serious points. Leave it sitting on the desk and walk away, and it may count against you. For Innes, it wasn’t about whether a candidate had mastered spreadsheets or could deliver a slick pitch, but whether they displayed the kind of team spirit and willingness to contribute to small, everyday tasks that define a healthy workplace culture.

Why attitude matters more than skill

“Skills can be taught, experience can be gained,” Innes explained in an interview. “But attitude—that’s what really counts.”

This approach underlines a growing trend in hiring: soft skills are no longer the “nice extras” they once were. Employers increasingly want to know whether you’ll collaborate well, adapt quickly and respect the environment you’re stepping into. Returning your cup isn’t about dishwashing; it’s about showing you’re mindful, proactive and considerate—traits that carry weight far beyond the kitchen.

The other hidden tests recruiters use

The coffee cup trick isn’t unique. Some companies quietly rely on what’s been dubbed the “receptionist test.” Here, the recruiter pretends to be the front desk assistant before the official interview begins. If a candidate is polite, patient and respectful, they start on the right foot. But if they come across as dismissive or rude, it sends an early warning signal—no matter how polished their CV may look.

These little experiments are designed to reveal qualities you can’t fake with rehearsed answers: kindness, humility, and social awareness.

A lesson for your next interview

So, what’s the takeaway? If you’re offered a drink in your next interview, accept it graciously—but pay attention to what happens afterwards. Asking where to put the cup, or simply offering to take it back, might seem trivial. But in some workplaces, it could tip the scales in your favour.

In the end, the coffee cup test is a reminder that interviews aren’t just about what you say under pressure, but how you behave when you think no one is watching. And sometimes, that empty mug tells a bigger story than any polished speech.
