Former ISS. Training is fine. Tests every morning, but you are well prepared before taking it. A lot of training on the full line from DES to balloons, to IVUS, to Rota...It's a good gig, but like another person said, do not get caught up with what the csr is or is not doing. Do your job and make some pretty good $. ISS has been known though to be RIF'd pretty often...
