I have a lot of people ask me about "outside the box" ways of reaching HR and Hiring Managers. One that comes up a lot is, "Should I use Google to find the recruiter's email address and circumvent the applicant tracking system?"
I appreciate the idea, but I think it is likely to work against you (if it makes any impact at all).
If a requisition provides details for submitting your application, you need to adhere to those guidelines. Not doing so essentially says "your guidelines don't apply to me." Probably not the first impression you want to make.
More likely, your resume will not make it into the company's applicant tracking system, which means you won't be even considered.
My advice – follow the outlined protocol. Target your resume toward the specific position, speak to specific accomplishments and clearly outline the value you intend to add.
That is what will get you noticed.
