A NOC would be a great place to start off for freshies. Would be best if you could obtain your CCNA beforehand as most of the interview questions would be based on the syllabus. Depending on your interests and job opportunities out there, you may want to specialize in either in routing & switching, security or voice. Just keep in mind that the networking world is pretty competitive and you'll need to constantly study new technologies and take certifications if you want to move forward in your career and not be stuck in some support role for the next 5 years.

Hope this helps!
