Tell Me About Yourself

Hello can someone help me. I'm applying for a job as a CNA and I'm getting ready for an interview. I just want to know what kind of information should I give or what the interviewer really wants to know about me. I never had an interview before this is my first time to get a job. I came here in the U.S 4 years ago and I'm still studying to improve my English. I just finished my CNA/HHA (Certified Nurse Assistant and Home Health Aide) course. I'm willing to accept new assignments and seeks out new experience. I'm a self starter, eager to learn and willing to be trained. I hope someone can help me. Thank you very much!
