Looking out for potential jobs: Most of the time, you're not going to hear about one potential job, apply for it, get it, and have it turn out to be perfect. (However, you may be lucky enough to experience exactly that!) The same goes for dating; right at the beginning, you're meeting various people, and you may not even know that you're looking for anyone just then!
Updating your resume/CV: Now that you know you're looking for someone, you're probably going to do some introspection; after all, how would you expect to meet someone who would work well with you unless YOU know yourself pretty well? Of course, the updating of the resume and CV also comes into play when you're trying to make a good first impression on your potential employer (significant other).
Applying: Maybe you've noticed some employers you'd love to work for; now, you need to get them to notice you! In terms of dating, this comes into play when getting to know potential dates a little better.
Follow up interviews: By this point, you've probably met many different people and been on some first (and even second) dates. You've narrowed down your list, and so have they. You're using the time you're spending with potential significant others to learn even more about them, and see whether the two of you would be a good fit.
Signing the contract: If the probationary period went well, then the both of you are ready for a longer-term commitment!
