They’re watching what you do with your coffee.
Across offices from Sydney to San Francisco, a small, apparently polite gesture at the start of an interview has become a quiet filter for candidates. The “coffee cup test” sounds harmless, almost cosy. For some jobseekers, it can be the detail that kills their chances.
What actually is the coffee cup test?
The idea comes from Australian executive Trent Innes, who popularised it during his time running software company Xero Australia. The set‑up is simple.
- The interviewer offers you a drink – usually coffee or water.
- You talk, you answer questions, you sell your skills.
- At the end, the interview ends…and your cup is still there.
From there, the hiring manager pays close attention to one tiny moment: what you do with that cup.
The unwritten rule: taking your empty cup back to the kitchen scores points; leaving it on the desk quietly counts against you.
Innes has said he used this as a final filter. If a candidate picked up their cup and asked where to put it, that signalled initiative and a willingness to pitch in. If they simply walked out and left it to someone else, he considered that a red flag about attitude.
Soft skills under the microscope
The coffee cup test taps into a much broader shift in hiring. Technical skills still matter, but they are easier to prove through CVs, portfolios and technical assessments. What is harder to judge is how someone behaves once the spotlight is off.
That is where these micro-tests come in. They try to reveal:
- Sense of personal responsibility
- Team mindset versus “not my job” mentality
- Respect for shared spaces and invisible labour
- Ability to read social cues in a new environment
Supporters argue that a small act, like clearing your own cup, reflects deeper character traits. They see it as a quick proxy for humility and collaboration, especially in companies that prize flat hierarchies and hands-on culture.
A harsh test or a clever signal?
The method has drawn fascination online, but also criticism. On the surface, it sounds almost childish: a professional future resting on crockery etiquette.

For many candidates, the troubling part isn’t the cup. It’s that no one tells you the rules of the game.
Critics raise several points. First, the test is culturally loaded. In some workplaces, leaving dishes where they are is normal, and an assistant clears rooms. In other places, putting your cup in the sink without asking might feel intrusive or inappropriate.
Second, power dynamics matter. A nervous candidate may worry about wandering around an unfamiliar office. Some people grew up being taught not to touch anything in someone else’s workspace. Others might be disabled or anxious about carrying hot drinks long distances.
There is also a fairness question. When you judge candidates on secret expectations, you tend to privilege those who already understand unwritten corporate codes – often people from more privileged backgrounds.
Other sneaky behaviour tests in interviews
The coffee cup test is only one example of subtle behavioural screening. Recruiters have quietly used similar tactics for years.
The receptionist test
One common variation is the “receptionist test”. Here, the hiring manager or a colleague observes how candidates behave before the official conversation starts.
Some companies brief reception staff to report whether a candidate was polite, impatient or dismissive while waiting.
Sometimes the interviewer themselves pretends to be a receptionist or assistant, greeting the candidate in a low-status role. The real test: does the candidate treat that person with the same respect they’d show a CEO?
Stories circulate of candidates who impressed at the table, then swore at security downstairs, only to find themselves quietly removed from consideration.
The small kindness audit
Beyond cups and reception desks, hiring managers often watch for micro‑behaviours:
- Does the candidate hold the door for someone behind them?
- Do they thank the person who brings water or sets up the laptop?
- Do they apologise if they are late, or blame traffic aggressively?
- Do they interrupt repeatedly or listen attentively?
None of these on their own should make or break a career. But together, they feed into an informal picture of how someone may behave once they join the team.
Ethical questions around hidden hiring tricks
Quiet tests like these raise ethical and legal concerns. Most countries do not regulate how someone treats a coffee cup, of course, but hiring processes are meant to be fair, transparent and related to the job.
When a recruiter bases a decision on a hidden ritual, three risks appear:
| Risk | What it looks like |
|---|---|
| Bias | Candidates from certain cultures or backgrounds are unintentionally penalised. |
| Lack of transparency | People are rejected without understanding the real reason, reducing trust. |
| Irrelevance | The test has little to do with actual job performance or core tasks. |
Employment lawyers tend not to focus on coffee etiquette itself, but on patterns. If hidden tests create systemic barriers for certain groups, companies could face accusations of indirect discrimination.
How candidates can respond in real life
Jobseekers cannot control which quirky ideas a manager has picked up from management podcasts. They can, though, shape their own behaviour without becoming paranoid.
A practical approach looks like this: assume small acts are noticed, but don’t obsess. If you are offered a drink, accept or decline calmly. If you do accept and finish it, you can simply say at the end:
“Where would you like me to put my cup?”
This balance shows consideration and respect for the space, while leaving room for the interviewer to say, “Just leave it there, that’s fine.” If they insist on handling it, you complied with their instruction. If they invite you to take it to the kitchen, you show you are happy to muck in.
Politeness towards every person you meet – from security to the CEO – is another low-stress rule that pays off beyond any secret test. It also means that, whatever informal notes go into your file, you can live with how you behaved.
What hiring managers should think about before using the test
For managers tempted by the coffee cup idea, there are genuine questions to ask first. Does this ritual actually predict performance? Or is it just a fun story to tell on LinkedIn?
Structured behavioural interviews and realistic job tasks usually give richer data: asking candidates how they handled past conflicts, or giving them a short case study that mirrors real work. These methods are more time-consuming, but they are also easier to justify internally if a decision is challenged.
If a leader still likes the symbolism of the cup, they could use it as a conversation starter instead of a silent judgment. For instance, noticing that a candidate hesitates and then asking how they usually handle shared spaces in past roles could open up a discussion about culture fit in a more transparent way.
Understanding “soft skills” and culture fit
The coffee cup debate hinges on two fashionable HR phrases: “soft skills” and “culture fit”. They sound vague, so they are worth unpacking.
Soft skills refer to non-technical abilities such as communication, empathy, adaptability and conflict management. They are harder to measure than coding ability or sales numbers, but they often decide who thrives once the job starts.
Culture fit is trickier. At best, it means alignment with shared values: respect, integrity, openness. At worst, it becomes shorthand for “people who feel like us”, which risks sidelining diversity and fresh perspectives.
Quiet tests based on cups, corridors or small talk easily blur these lines. They might signal genuine alignment with a collaborative culture. They might also reward candidates who simply grew up in similar offices or social circles.
A brief thought experiment for jobseekers
Imagine two candidates for the same role.
The first is technically brilliant but visibly annoyed when offered coffee, leaves the cup on the table and barks at reception on the way out. The second still has learning to do on some tools, but listens closely, thanks staff and instinctively asks where to put their mug.
Most teams know which person they would rather sit next to every day. The challenge is designing hiring processes that reach that conclusion openly and fairly, without relying on secret traps about crockery.
