The current state of the job market has left many feeling uneasy about what the future holds in terms of finances, career goals, and overall growth; not to mention the rise of never-ending rounds of interviews, just to often end up right back at square one. 

However, not all employers will require you to jump through hoops for them during an interview. In fact, one boss unveiled a secret yet effective approach he often uses in interviews to assess if a given candidate has the right attitude to fit in with the company’s culture. And it all starts with a cup of coffee.

A boss uses a secret ‘coffee cup' test during interviews and refuses to hire anyone who doesn’t pass.

Trent Innes, the former managing director of Xero Australia, which is an accounting software company, shared in a resurfaced 2019 business podcast “The Ventures” that he tests his candidates with a cup of coffee, or any preferred drink, and bases his hiring decisions on what the candidate does after they’ve emptied their cup.

In the podcast, Innes explained the beginning of the test, “If you do come in and have an interview, as soon as you come in and you do meet me, I will always take you for a walk down to one of our kitchens and somehow you always end up walking away with a drink.” 

After accepting a drink, the candidate is then taken back to the interview site. Throughout the interview, the candidate will gradually sip away at their drink (perhaps to wash away nerves or replenish their emotional stamina) until the interview is over. At the end of the interview, the employer observes what the candidate does with the empty cup.

Innes explained that at the end of these interviews, one thing he always accounts for is, “Does this person doing the interview want to take that empty cup back to the kitchen?” The answer to this is entirely based on the candidate’s actions, which also largely determines whether Innes believes the person is the right fit for the job.

The way to pass the test is to simply offer to return the empty cup to the kitchen.

The former managing director explained that by doing this, the candidate has the opportunity to express their enthusiasm to join the company while leaving a lasting impression. 

“You can develop skills, you can gain knowledge and experience, but it really comes down to attitude, and the attitude that we talk about is the concept of ‘wash your own coffee cup,’” he stated. “You really want to make sure that you’ve got people who have got a real sense of ownership, and that’s really what I was looking for.”

For those who have interviewed with Innes, about 10% failed the test by not offering to return their cups to the kitchen. “The really pleasing thing is a vast majority of people do,” said Innes.

Of course, possessing the skills and experience for a given company undoubtedly stands as a pivotal attribute that can land you a job, but a positive attitude is arguably just as important, and the coffee cup test evaluates this. 

He said he also used the secret test to measure whether a candidate would "really take on everything that they should be doing." And that statement right there is where his "test" went awry with experts and job seekers alike. While testing for a personality fit makes sense, testing to see how agreeable or amenable someone is to potentially doing things they don't want to do or shouldn't be tasked with is problematic.

Many argued that Innes’ seemingly arbitrary approach isn’t a fair assessment of a candidate’s ability to be a team player. 

As one person on Reddit thoughtfully pointed out, “Every human is going to be so nervous in that situation. There aren't many humans who will take a cup from the kitchen all the way back to some dude's office, wrap up a tense interview, and immediately go ‘Well better make my way back to the sink to do some dishes real quick.’”

Victoria Gates, an interview and hiring expert, was so troubled by Innes' secret trick that she took to TikTok to share her thoughts. She said, "What interviewers need to understand is attitudes and actions are best evaluated with actual job-related experience and not made-up social experiments." Adding, "Candidates have choices, and if you find out that you didn't get a job because of this weird social experiment, you're probably better off."

In a tight job market, the interview process can be an incredibly stressful time after long nights of preparation. Ultimately, placing unspoken expectations on candidates not only wastes their time and money but also the company’s as well.

Forcing candidates to worry about arbitrary rules regarding social norms and manners is unfair to anyone who was taught differently. As TikToker Ali noted in a video on the topic, she would have assumed that it was gauche to go back into the employee kitchen following an interview because it would be inappropriate to wander through an office where you weren't employed. She also pointed out that she was taught as a guest, which is basically what a job candidate is, that etiquette would dictate you don't even offer to clean your cup. That could certainly seem meek and deemed bad manners. Both qualities that no job candidate would want to convey.

Maybe the true test is always to say no when offered a drink of any kind before an interview.
