According to me, knowledge on User Experience will develop only through practice. Books, Courses etc can teach only the techniques but when to use the technique and how to analyses the outcome etc will comes only with experience. Slowly our assumption about users, would fade away and start understanding the actual needs of them. Once we reach that stage, we would become the most important person on the project and an irreplaceable asset for the company.
Now coming to the point, "YES. It is possible to become UX Designer as a fresher". Several MNC companies do hire freshers. But if you are not from a premier design institutes, it is going to be difficult journey for you. Even if you can land in a job, it would take some time for you to understand the role and start contributing to the project. Be aware, several company won't have a dedicated team for UX, you have create your own process and set your deliverables. Hence, It is very important for you get prepared for it and learn all the technique you required thoroughly. You have to be very confident about your knowledge and the strategy. Ideally UX is a pre project activity but most of them time you might end up working on parallel with development. You will not get time to learn anything new.
You can learn UX by reading online articles, taking physical courses etc or as an alternative you can find a mentor who could help you on understanding your role and the contribution. At least for the first year you would need his/her guidance. You can use the mentor expertise to understand the user problem and to get suggestion about best technique for a use case.
Being myself a UX designer working for more than 7 years now, I do mentoring for the student who aspire to become UX Designer. You can email me at snmbala@gmail.com or call +91 9902398198
