My question is somewhat opposite than most people would expect. So here it is...
Last year, I was thinking to make a career transition into some very specific management kind of roles from an Engineering background. During the same time, some recruiters from top-notch tech companies contacted me for some great engineering career opportunities (same kind of role/track that I am doing currently). I respectfully turned them down saying that it does not match my future career goals although the position is very lucrative in terms of recognition and financially. Note that I turned it down right at the onset i.e. without doing any telephone or in-person interviews which kind of made sense since I did not want to waste anyone's time.
Now after researching a bit more, I found that I need more experience to be in the kind of roles that I have been targeting and after doing some information interviews the general idea was to continue doing similar type of work (engineering) for few more years and then try again.
So my question(s): Is it OK to contact those specific recruiters again. I understand that those position might not be available anymore but I want to make myself available if any such future opportunities arise. Also, what and more importantly how should I say tactfully that why I am interested again? What are the chances that they may take me seriously? I would really appreciate if anyone has been in a similar situation and have been successful at it.
EDIT: Most of the recruiters that I talked about are recruiters working for the company and they are not necessarily 3rd party contract recruiters.
