Sticking 100% to the Job Description is like putting all eggs in one basket
It’s a classic situation, hiring managers focus on the job description and will just reject anybody that doesn’t perfectly fit = doesn’t comply with each and every requirement.
A recruiter must by all means fight this kind of attitude. One sign of a healthy and innovative organization is the fact that it accepts diversity and adapts and is able to find new interesting competencies that they were not initially looking for.
Having said this, it’s not about imposing just about any candidate to the hiring manager just because. It’s about truly knowing the organization and the department that you’re hiring for in order to really help them find talent that will make them be more successful.
