It depends on your interest. If you want to pursue a career in the technical field than GATE is a good choice, a good score in GATE will open your options to get in PSUs. If you want to get a work experience then job is better, even after working for 1-2 years you can appear for GATE and complete M.Tech to enhance your skills.

GATE aspirants follow different strategies for success, but there is no magic formula guaranteeing GATE exam success. Experts agree that only hard work, planning and starting early, will maximize the chances of success.
A recognizable score in GATE offers a kick start to the career of the student. GATE exam happens in the month of February, i.e. during the last semester (8th) of engineering. Hence, a student will have only six month, if he starts preparing in the 4th year of engineering. Most students are baffled as to when they should start preparing for GATE exam. Experts says that 3rd year is the best time to start GATE preparation.

On what basis are you preparing for GATE? You have to complete your graduation first.
