It depends on the industry in which you are applying and the country!
In the USA - most engineering companies recognize the FE (fundamentals of engineering) as well as PE (professional engineering) certifications. More details on those exams/certificates are available here: http://ncees.org/ .
Also note - many USA companies do not require the FE or PE for hire. While certifications look good on a resume, many mechanical engineers do get jobs and have jobs despite never taking the FE or PE exams.
If you are curious about specific companies' practices, I would suggest looking at their LinkedIn information or at a website like www.glassdoor.com which can give more of "insider" opinions on how a specific company works. Hope that helps and best of luck to you!
