Tech exec says the most overrated piece of job interview advice is taken 'too seriously'.

According to Gillian Munson, you may not need to wear a suit in your next job interview.

Munson, Vimeo's CFO, advises that dressing for the desired role doesn't always require formal attire.

It's advisable to wear less formal attire during interviews, especially in the current era of virtual interviews, according to her.

Munson feels that when candidates are interviewed remotely, they may not appear as confident and professional as they would in person. She advises that people should not take their appearance too seriously when seeking advice.

She prefers to evaluate individuals when they are at ease and self-assured, allowing her to make more accurate predictions about their performance as employees.

Munson advises a more relaxed dress code while maintaining reasonableness. She emphasizes the importance of showing respect for the role, regardless of the interview setting, whether it's in-person or via Zoom.

How to figure out the company's dress code

The dress code for interviews can differ based on the job and company culture.

Dressing appropriately in an interview is important, advised Farah Sharghi, who recommended dressing one notch more formally than others at the company.

For a more conservative interview, opt for a button-up shirt, trousers, and nice shoes. For a startup interview, a collared shirt and khakis can be a smart choice.

To determine what to wear for an interview, Sharghi advises asking the recruiter, who, as an insider, can provide information on the workplace's dress code.

"It's advisable to follow a recruiter's guidance," she stated.
