There is a bias against certifications by some (but by no means all) professionals in InfoSec, since it is a heavily "hands-on" field. There is more emphasis on demonstrating actual ability through CTFs, bug bounties, published exploits, etc.
However, unlike Certified Ethical Hacker, CISSP, and other "mile wide, but inch deep" certs, the OSCP is a heavily hands-on certification that tests actual ability. No knowledgeable employer would discriminate against you for earning it.
And CISSP or CISSM are valuable if you're applying for a management job. For government defense-sector jobs, they are often required.
