Your chances of receiving (or not) of an RFE or interview are pretty much even. If the officer adjudicating your case feels the need to get the latest empl. letter or transfer the case to a local office for interview, he/she will do so. Going by the trend lately, its tough to make that call. For all you know, you might just getting the approval without anything.
Nothing to get desperate about.
In the meanwhile, try your best to get a job ... even a temporary one as a consultant or some sort and be on a payroll asap. But again, don't get desperate. Things will work out just fine.
Good luck in your job search.
