I second that opinion. I also came to nursing as a second career and did not work as a CNA first. I can look back and see how much that experience would have helped me. By working as a CNA, you'll get familiar with the whole healthcare environment, including the jargon, supplies, dealing with patients, etc. As far as that person who told you they prefer someone without experience so they can train them how they want....that's ridiculous. Everyone does things a little differently. You'll find out what works for you and what is acceptable at your workplace. Prior experience can only benefit you.
