If you are offered a beverage during a job interview, water you going to do?

Employees have revealed the secret hiring tests that managers use to determine whether a candidate is fit for the job — and they include such methods as the “water” test.

In a resurfaced Reddit thread, a user asked hiring managers to reveal the “special tests” they put interviewees through “without their knowing,” a query that yielded hundreds of responses.

One respondent said their hiring manager uses a “water” test, in which “they put a jug of water with a cup out to see if anyone would drink it while being interviewed.”

“I was the only person who drank the water at a ‘normal pace’ during the interview, and this is seen as being ‘confident in the workplace environment by accepting a gift or offer,'” they explained, adding that their “normal pace” was taking a sip after answering each of their questions.

“Apparently, you can tell a lot about a person from the way they refuse the offer of the water or by drinking it too fast.”

Readers couldn’t believe the method was used to determine candidacy for a job, with some saying their gut instinct would be to refuse the beverage out of fear of leaving a lipstick stain or having to use the restroom.

“Lipstick stains are embarrassing, and most interviews are 30-60 minutes, I wouldn’t get exceptionally thirsty, and what if it made me have to pee?” wrote one person. “Also, I can keep my voice utterly calm and pleasant even when I’m totally freaking out in my head, but my hands sometimes can have a little bit of a tremor. Not good circumstances for drinking water!”

“I would hate this … I always drink fast, it would easily be misinterpreted,” another chimed in.

“This is an unbelievably f – – king stupid way to find employees,” chided someone else.

Other ways hiring managers secretly tested job candidates included taking them to lunch and observing how fast they chose a menu item or how enthusiastic they were about their hobbies.

“Not me, but my grandfather. He started a fairly successful business for himself and he said that whenever he considers hiring someone, he takes them out to lunch,” one person wrote. “If they take more than a minute or two to pick something off the menu, he won’t hire them.”

“I would ask about hobbies and then ask an uninformed (but hopefully not insulting) question about their hobby, even if it was one I was into myself,” another user said.

“The goal was to see how they responded. Some people would make me feel stupid for not knowing something they knew. Most would politely answer and maybe explain a thing or two. The really good ones would treat me like one of the lucky 10,000 and actually get me excited about their hobby.”

One former restaurant worker recalled how his boss would redirect inquiring applicants to enter through the kitchen door at the back of the eatery rather than the front entrance.

“As they were walking around the building, he would dash to the kitchen and lay a broom across the floor, just inside from the door,” the user said.

“If the applicant entered through the back door normally, he or she was given an application to complete and then sent away. But if the applicant entered through the back door and picked up the broom to stand it with the other brooms, he or she was hired on the spot.”

The arbitrary trials are similar to those of the controversial “coffee cup test,” used by a manager who would offer applicants a mug of joe in the office kitchen before sitting down for the interview.

After they were done, if the prospective employee did not offer to return their used cup to the kitchen, they were unlikely to be hired.
