The firms try to do cost cutting by paying low wages to freshers. You need to remember that your initial wage decides your later progress. You need to negotiate to make sure you get a decent first salary. You may have a tough time convincing the interviewers why you deserve the pay you are quoting. Freshers are just out of the college and they lack work ethics or understanding of the work culture. The company has to spend time, money and effort to train freshers into eligible employees. This is the reason why the companies are hesitant to pay a good wage to a fresher. If you negotiate well and are able to convince why you deserve a better pay, you may get the pay you have quoted.
