A majority of hiring managers view a lack of enthusiasm as a warning sign: "It's crucial to convey your motivation."

To ensure that a candidate is genuinely interested in the position, a company seeks confirmation when hiring.

A recent LinkedIn survey of 1,024 hiring managers found that nearly half, 47%, consider a candidate's enthusiasm about the job as the most important factor when making hiring decisions. Similarly, 46% ranked the quality of a candidate's responses as critical, while 45% emphasized their soft skills. On the other hand, 54% of hiring managers believe that a lack of enthusiasm for the job can hinder a candidate's chances of advancing in the hiring process.

"Drew McCaskill, a LinkedIn career expert, states that when working with a diverse group of individuals and having the option to select, you will choose those who demonstrate engagement."

Here's how to show that enthusiasm.

'I'm going to put my best foot forward'

There are numerous methods to demonstrate your enthusiasm for the job during the interview.

McCaskill advises appearing professional on video, being engaged, and knowledgeable about the company during an interview. He suggests asking the interviewer questions about the role.

To make a good impression and show professionalism, McCaskill advises sending a thank you note after the interview, whether through snail mail or email. The note should reinforce your interest in the role and why you would be a good fit.

He remarks that the practice is tried and true in an old-fashioned way.

'You have to give them your why'

Directly expressing your enthusiasm for the job is the best way to convey it to your interviewers.

McCaskill advises job candidates to convey their desire for a role during interviews by expressing it to the recruiter or hiring manager. To contribute to the business and help the team achieve its goals, candidates should specifically explain how they can add value and make a positive impact in the role.

Why does the role speak to you? Do you connect with the company's mission? Are you passionate about the problems it's solving?

"You have to give them your why," says McCaskill.
