Getting invited to a job interview is an accomplishment in itself, but it's only one step in the hiring process. Employers use interviews to evaluate much more than your resume. They want to understand how you communicate, solve problems, fit within the organization, and represent the company.
Many highly qualified candidates lose opportunities because of avoidable interview mistakes rather than a lack of experience or technical skills. Arriving unprepared, giving vague answers, speaking negatively about previous employers, or failing to demonstrate enthusiasm can all influence a hiring manager's decision.
Fortunately, interviewing is a skill that can be learned and improved. By understanding what employers are looking for and avoiding common pitfalls, you can present yourself more confidently and significantly improve your chances of receiving a job offer.

Strong interview skills help employers feel confident that you'll represent the organization well and contribute positively to the team.
