Confidence coach: Goodbye imposter syndrome, hello career success

You’ve finally landed an interview, or maybe even your dream job, but now you’re questioning whether you really have what it takes, can’t seem to string two sentences together and have no idea what to wear. Dealing with nerves while navigating the job market can be tough, but the good news is it’s not impossible.

Here, careers expert and psychologist Suzie Plush reveals everything you need to know about boosting your confidence in the workplace – and how to overcome performance anxiety for good.

What makes for a great interview or first-day outfit?

“The key is choosing something that fits well, reflects your style and gives you a sense of ease,” Plush says. “Wearing something you’ve worn before and felt confident in is ideal. It links you to a moment where you already felt capable and grounded.”

It’s also a good idea to coordinate your outfit with the company’s dress code. Do they lean more casual, or do they stick to corporate wear? “This way, you can show up feeling prepared and aligned with the culture,” Plush explains.

To add to that confidence, especially in close-contact interview settings, quickly rinsing with Listerine can ensure you feel fresh and ready to make a positive impression.

How can I feel more confident during an interview or on my first day?

“One of the best ways to project confidence is by being well prepared,” Plush says. “The more grounded you are in your story, skills, achievements and values, the more you’ll be able to steady yourself if anxiety creeps in.”

Your body language also plays a powerful role. “One simple tip is to take up a little more space,” Plush adds. “Sit or stand with presence rather than shrinking into yourself. These small shifts don’t just change how others see you – they also help you feel centred and calm.”

What’s the best way to manage pre-interview nerves?

According to Plush, movement is key. “Go for a short walk, stretch or shake out the tension,” she tips. Once you’ve worked out the jitters, it’s time to calm your mind.

“Box breathing is simple but incredibly effective,” Plush says. This technique involves inhaling for four seconds, holding the breath for four, exhaling for four and holding again for four. “It settles the nervous system and gives your mind something to focus on,” Plush explains.

I’m worried about tricky questions. How can I best prepare for them?

Feel as though you’re walking into a trap when someone asks about your biggest weakness? These questions aren’t setting you up for failure, Plush assures – they’re about understanding your level of self-awareness.

“The best answers are honest but thoughtful,” she says. “For example, ‘I can get stuck in the details and sometimes spend more time than needed on tasks, but I’ve learned to set clear time limits and check in with colleagues earlier because of it.'”

There is no need to answer each question perfectly – just show your potential employer that you can be honest, open and reflective.

How can I make a great first impression on a new or potential employer?

You don’t need to be the loudest person in the room to be remembered. “It’s about being present,” Plush says. “A warm greeting, good eye contact and listening with curiosity goes a long way.

“Ask a thoughtful question or show genuine interest in the person or organisation. If you can leave someone with a sense of calm confidence and kindness, that’s a first impression that sticks.”

It’s also important not to downplay your ideas, apologise unnecessarily or hesitate to speak up. As Plush notes, “Avoiding eye contact, slouching or fidgeting can send mixed signals. When your words, tone and posture align, people are more likely to trust and listen to you.”

What’s the best way to build confidence in a new role?

Don’t underestimate the power of forming connections with your colleagues – it can make a new environment feel less daunting.

“Introduce yourself, ask people about their work and take an interest in the culture,” Plush tips. “Feeling psychologically safe, like you belong, is the foundation of real confidence.”

After that, Plush says to set a few achievable goals. “They don’t have to be big wins – just little moments of progress. Confidence often comes after we take action, not before.”

How can I beat imposter syndrome?

We’ve all been there – one minute you’re celebrating a career achievement and the next you’re feeling like a fraud. According to Plush, the key to overcoming this feeling is to acknowledge the doubt but don’t let it hold you back.

“Instead of arguing with the voice that says, ‘You’re not good enough,’ try simply noticing it,” she explains. “That small bit of distance can stop you getting caught up in it.”
