So, long story short - about 10 months ago I was seriously contemplating quitting my job and I noticed that one of my LinkedIn connections (recruiter from an hr agency) posted a job that looked like a good fit for me (to give some further background - I'm working as a software developer).
I contacted the recruiter and interviewed with the company (and even received an offer, but it was no better than my current position, so I turned it down). After that, the recruiter started sending me information about some other available positions, but I told him that I'm not interested in them. Nevertheless, I started getting emails from other recruiters from the same agency and at some point I believe I got into some kind of candidate database and thus started receiving multiple messages/emails daily from recruiters from other agencies, hrs of software companies and so on.
However, in the meantime I got transferred to a new project at my current job and decided not to leave for the time being. So I ended up not really looking for a new job, but receiving many job offers from here and there. In the beginning I was replying to everyone, thanking them for their interest and stating that I'm not looking for a new position right now, but at some point it was just taking me too much time and I stopped doing it. Now, I'd like to interview again, but I'm a bit ashamed to start contacting recruiters (and even applying at some companies) after not responding to their emails for months. How should I go about this? Should I be worried?
