Which is first job or certificates

Here goes a question I have in my mind after I finish my study and start looking for a job.

I have visited many recruiting websites and also clicked on many career tabs on companies websites.

There I have read many responsibilities and duties sections, which some the vacancies' duties seem new to me-where can I learn as fresh graduate about all those functions/terms used- but some of it-Oh man this guy is talking about me he is just reading my mind and knows my skills- makes me DROLL. But, suddenly I read MINIMUM EXPERIENCE 1/2/5 or maybe tens of years. and that is besides the question for certifications.

I do have studied CCNA and CCNA security but never apply for the certificates. My masters was CISSP curriculum, but no certificate too.

Now that after I saw these...

I wonder should I go for certifications and spend time and money to get certified while searching for a job??

Or should I just find any chance and then get certified along the way. Because I'm afraid if getting the certificate will not help without the working experience

I guess I'm not alone having the problem so I hope useful answers that can make this question beneficial for all

Thanks
