Is LinkedIn the only way?

So if I want a job, without reference, without college placements. is LinkedIn the only way? Like if I have certain set of skills and degree how do I approach the companies or how will the company approach me. I don’t use websites like Naukri.com or LinkedIn. Job dhundhte kaise hai? I am 24 I have zero experience as I’m pursuing CA, and haven’t cleared CA inter yet so no job till now..
