For the OP, we haven't met, so I may be making an incorrect assumption here, but...
It seems that you may be a bit concerned that you will have to do a sim eval as part of a job interview soon and it has you on edge ( given your previous experience with one, and your time away from flying the past few years ).
Aside from getting some flying in to knock off the rust, and a flight review I would suggest taking the opportunity to get some time in a GTD such as an AST 300, with an instructor. Maybe start with the basics ( attitude instrument flying ), zero turbulence at first, then crank it up!
Next practice some approaches, same as the BAIF, and after you're back up to speed on that have the instructor throw in an unexpected hold here and there.
Step 1 is to get the negative experience from the past out of the front of your mind, it'll never completely go away, but don't let it intimidate you, use it as motivation instead!
There is a great group of people on this site, and if you're capable of doing the job and have a good attitude I think you will find that very few people here wouldn't honestly want you to succeed, in fact they'd be thrilled to see you do it and would be happy to be your co-workers!
I think Billy Maddison summed it up pretty well when he described the responsibilities of a pet owner.
If you really want this then make it happen.
