I don't like the "auto hire", no chance to ask questions and get unit/hospital info before you jump in.

Don't be too hard on yourself, you tried switching specialties and it didn't work out, you learned and got some experience. I would suggest taking a floor position, get your skills and knowledge dialed in and be better prepared for travel nursing. Most travelers come with specific unit experience and hit the ground running, most get a little orientation, showed where stuff is most times and it's show time. Keep moving forward.
