How to find a sponsered full-time job after graduation?Watch
Are you in the UK? You don't need a sponsored visa any more, at least for the first 2 years of employment, as you'll be on the Graduate Route visa. After that yes, you'll need sponsorship but perhaps you'll be able to prove to an employer that they need you by that time. What you do need to do is network HARD especially in that line of work, and seek out smaller companies who might be willing to give you a chance. Alumni are a good place to start. Good luck!
