I am currently about a year from completing my Bachelor's in Software Engineering. I was recently contacted via email by a recruiter for a third party. They said that they found me via LinkedIn, and included the job description. I have been contacted previously by startups, but this is the first time I have been contacted by a recruiter. So, I am a little confused regarding the appropriate next steps.
For one, its not even clear whether the offer is an internship or a job and the duration, but the company (from Google searches) seems to be a fairly fast growing company.
So, what is the process now? If I am not interested, should I reply with a short email stating I am not interested? On the other hand, if I were interested, what would be the next steps here?
Moreover, given that the company has the job listing available on their company page, what's the purpose of the recruiter? I mean, I could just as well go to the company page and directly contact them, from here on.
My main interest here, is to know the process, rather than what to do in this specific instance.
