Going back to your plan, consider the jobs that you have a decent chance of getting. Nothing annoys recruiters more than seeing the same cv coming in for many different jobs across the recruitment spectrum. When this happens the recruiter has no choice but to think that the candidate really hasn’t got a clue what he or she actually wants. Besides all you do is confuse yourself.
Fair enough, it is possible that you have a couple of different interests. Just make sure that they’re jobs you do have a good chance of at least getting interviews for and that your applications do you justice. Be focussed.
