If every job requirement is in need of people with lot of years experience, how then can the freshers be employed?

One good option for newcomers is to start with an internship. Recently graduated with no previous experience should look for an institution they are interested in and apply for an internship. This period of time will show your skills, your learning skills and will enable yourself to enter the labor market in the future. 

Networking is another option. Today, students and recently graduated should engage in volunteering or self-made initiatives. For instance, having a blog or being active on social media. Everything communicated and social networking can also be a step stone for future projects.
