Always say 'yes' when asked this one job interview question, expert advises

If you want to make a good impression at your next job interview, this "psychological hack" may come in handy.

One career expert says if you're ever asked this one question in an interview setting you should always say 'yes'.

It's a simple move she says can have a big impact on what the interviewer thinks about you.

The question is simply: "Would you like a drink of tea or water?"

Employment coach Jackie Racine, who shares her top job-hunting and career tips on social media, explained in a TikTok video that if you're ever offered a refreshment at the beginning of an interview you should "always say yes"

She says her theory is backed by behavioural science with something known as the Ben Franklin effect.

"This theory kind of suggests that when someone does a favour for you they tend to like you more afterwards," she explains.

"So think about it this way, someone has to feel that they like you in order to do this favour for you so it plays a little trick in their mind, 'Oh, I've done something for this person, I do like them, I do have a positive perception of them'."

The Ben Franklin effect is a psychological phenomenon named after Benjamin Franklin, one of the founding fathers of the United States, who wrote about the concept in his autobiography.

"He that has once done you a kindness will be more ready to do you another, than he whom you yourself have obliged," he wrote.

Racine says this one thing "may seem really, really small" but it can make a big difference.

"It's like a weird little psychological hack that could definitely help you on your next interview," she says.

While this trick is handy, you also want to be mindful about what you do with your glass or mug once the interview is over because your interviewer might be testing you.

Some interviewers set up little 'tests' to see if the person sitting across from them is one they want to hire.

One example is the 'coffee mug' test employed by Trent Innes – former managing director of accounting platform Xero, now chief growth officer of hotel commerce platform, SiteMinder.

Innes shared the sly trick, one he's used on every interview candidate, in a 2019 interview.

"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," he told business podcast The Ventures.

"Then we take that back, have our interview, and one of the things I'm always looking for at the end of the interview is, does the person doing the interview want to take that empty cup back to the kitchen?

"You can develop skills, you can gain knowledge and experience but it really does come down to attitude, and the attitude that we talk a lot about is the concept of 'wash your coffee cup.'"

The act of wanting to tidy after ones self is something Innes believes contributes to the 'culture' of a workplace and notes the seeming success of his tactic as the office kitchen is always tidy.
