How to start working when every job needs 5 years of experience?

You will hardly find a job designed for fresh graduates. Therefore, apply for any jobs which require experiences. Employers may look at it and if the CV was attractive so employers  may conduct an interview with you. Once, you reached the point of interview, you could work on yourself and enhance your abilities and skills especially communication and interfering skills. Jobs will come to you if you are a qualified candidate. Good Luck
