This is going to sound obvious, but you’d be surprised how many people make this mistake when they walk into an interview for a job: they never bothered to research the company.
When you get the dreaded question, “why are you applying for this position?”, do you know enough about the company to answer confidently? Imagine the impression that interviewer will have of you when you say, “I am interested in this position because of the company’s mission statement” or “I enjoy the field of _________ and this position offers many opportunities in that area”.
It is important to know at least the basics about the company, its structure, and its stated mission/goals/purpose. The person who is interviewing you is attempting to discern if you will fit into their company culture and become a viable team member. They want to know that you care enough about the job. By demonstrating you’ve taken the time to learn about the position gives the interviewer an idea of what kind of employee you’ll be.
When you are acquainted with the company you are ready for the interview. If you are asked “Do you have any questions?,” you can intelligently respond with queries that show you did your homework. You are aware of the size of the workforce and the structure of the management team. You know the stated goals of the organization.
Researching the company before the interview is worth every minute you invest because it prepares you for anything you may be asked.
