hi candidate,

By qualifying Gate your chances of recruitment increases as it shows your technically sound. You can mention in your resume that you are GATE qualified and also can mention the GATE score if its good enough. Apart from increment in chances of getting a job/better job, there is nothing extra. Though you will be more technically sound then your colleagues and know the concepts better than who can't qualify GATE exam.

I hope this answer will help.
All the best for the future!!
