A hidden job is exactly that. It is hidden away, and doesn’t appear all over the Internet on hundreds of job boards attracting thousands of applicants.
Don’t forget, the objective of sending in a resume is to capture the attention and interest of the Hiring Manager and to get a telephone or face to face interview. Follow up is critical!
Everyone discourages phone calls but that isn’t going to frighten you is it? I’m sure the company wants to hire go-getters; people excited about the job opportunity!
