My suggestion to the job seeker would be not let the bird in hand for a better bird in the sky.
The jobseeker has already applied twice and was also given an opportunity of an interview. The company might have strong reasons for not considering the jobseeker. In turn, the jobseeker might just inform the interviewer that she had applied for that position earlier. If the jobseeker had realised her mistake made in her earlier interivew like not having adequate experience or skill and has worked on it; she can also mention that to the interviewer.
The interviewer can check with the earlier records on what basis she had rejected the jobseeker. If the reason is valid even for this instance she might just look at the examiner's position for the jobseeker.
But if she does not match the competency required for the analyst's position and get just the examiner's position she can definately work her way up to that post. It might take some time but the wait would be a justified one.
