I am new in the tech industry and am applying for my first real position. I've noticed there are a lot of recruiters and this is something I'm not very familiar with. It's my understanding that there two types of recruiters: those who work for a recruiting agency and those who are in house and work for the company they recruiter for. What I don't understand is, how is an in house recruiter any different than just a normal hiring manager? Is it because they only bring in candidates but don't actually evaluate them?
This job posting contains an example of my confusion https://www.cybercoders.com/jobs/details/324117/ In what sense is Ms.Lazarus the recruiter if I just found the posting myself? When I write a cover letter I normally start with "Dear Hiring Manager" but if she is the one who's going to be evaluating, should I address it to her? If she's not the one evaluating, then how does she fit in to the hiring process?
I have worked with a few recruiters before and the way things worked with them is they found job openings related to my skill set and they would discuss the position with me and then send the company my resume/cover letter. This is why I'm confused with the linked to posting, if I'm just applying by myself how does recruiter fit in?
