When it comes to job interviews, we pour over every detail available – our resumes, cover letters, and of course most importantly, what to say during the hiring process.

Not to mention, the effort we go to ask the right questions, so we can impress the future employer.

But have you ever wondered whatnotto say in a job interview?

Because according to some of the many business executives and managers we've spoken to, there are a few key things to steer clear from. According to research, three of the key reasonings behind job rejections are the following:

1. A lack of relevant professional experience.

2. Candidates not displaying enough knowledge about the company they are interviewing with.

3. Candidates not realising their social media platforms are looked at carefully by the company they are interviewing with.

With this in mind, we asked some bosses and business owners in Australia to share with us what their biggest turn-off is during a job interview.

Here's what they had to say.

Elle Ferguson, founder of ELEFFECT.

For Elle, she toldMamamiathat research is key – and to know how to pronounce the name of the company you are interviewing for!

"The biggest turn-off for me, as a boss is when people haven't done their research. You need to know the brand. Google is your best friend, watch videos of the brand so you pronounce the name correctly (yes believe it or not I have had people in interviews actually pronounce the brand incorrectly). Take notes of milestones in the business and what YOU love about the business. It's the biggest turn-off when people sit in an interview and know nothing about the brand. I think to myself, 'why are you here?'"

Mai Aristoteli, the General Manager of Elevate Communication.

According to Mai, not asking any questions is a big no-no.

"At the end of every interview, I ask 'What questions do you have for me?' I deliberately keep the question open, to encourage questions – any questions! When someone says they don't have any, this tells me that they aren't truly interested in the role, or they find it hard to connect and engage with others," Mai said toMamamia.

"If you can't think of a question about the role, you can simply ask them 'What do you love most about working here?' This gives you an insight into their values and the company – and added bonus, people love talking about themselves so they'll look back on the interview more positively!"

Some examples you could go with include:

Laura Thompson, founder of The Koori Circle and co-founder of The Clothing Gaps.

"We love getting a chance to meet and get to know new people throughout the interview process. We do our best to make people feel comfy while we try figure out if they are the right fit but, sometimes we raise a few eyebrows," Laura said toMamamia.

"One question we ask to all the people we interview is about their connection to the local Victorian Aboriginal Community because we are based on Wurundjeri Country in Melbourne. It's a bit of a turn-off when they miss the specific reference to 'local' and go on to tell us about their time working or visiting remote Aboriginal communities up north."

Laura also said that when hiring for Clothing The Gaps, it's imperative that people be immersed and engaged with Indigenous issues and causes. Because if the candidate is not, it shows.

"NAIDOC week is such an important time for Aboriginal and Torres Strait Islander people. So, it's also another turn off when a candidate can't correctly pronounce the word NAIDOC (NAY-DOC) and say 'NAR-DOC' instead. It makes you question their level of engagement and exposure to mob."

A food and beverage manager in the hospitality industry in NT.

"The hospitality industry is hard - no doubt about it. Given the challenges the industry is currently facing, with multiple job vacancies and not enough staff to fill them, it's been a tough slog for all. But a red flag for me is when the person I'm interviewing s**t talks their previous employer.

"I've conducted lots of interviews where I ask the candidate 'why are you leaving your current position?' or 'why did you leave your last job?' And their response is often make or break. What I would suggest people say is something along the lines of 'I decided to leave to pursue different career opportunities' or 'it was the right time' etc. Respect and professionalism is key."

Holly Wainwright, Executive Editor at Mamamia.

"There is only one thing someone can do in an interview that completely puts me off – knowing nothing about the place you're applying to," Holly said.

"Obviously, I don't expect a depth of knowledge or for someone to have done three weeks of unpaid resea
