Hey there!
Greetings.
Here you can check the below advantages of clearing Gate-
The GATE advantage

In this context, the following points are worth noting about this examination:

Many public sector undertakings such as BHEL, Indian Oil Corporation, NTPC, Bhabha Atomic Research Centre (there are PSUs totalling 217 in number) are using the GATE score for selecting candidates for their organisations. Students who qualify in GATE are entitled to a stipend of Rs 12400/- per month during their M.Tech course. Better remuneration is being offered for students of M.Tech/M.E as compared to those pursuing B.Tech /B.E. A good GATE rank assures a good job. After joining M.Tech. at IITs and IISc, one can look at a salary package ranging from Rs 7 lakh to 30 lakh per annum, depending upon specialisation and performance.

Clearing GATE is also an eligibility clause for the award of Junior Research Fellowship in CSIR Laboratories. M.Tech. degree is mandatory for those wishing to apply for research positions in R&D centres. The GATE score is valid for two years and those who qualify this test are eligible for doing Masters degree at NUS, (National University of Singapore), Singapore. A GATE score definitely gives one an edge when it comes to joining reputed companies as well as off-campus recruitments. For those who couldnt pursue their BTech in IIT, it provides another opportunity to study in the prestigious IITs. Above all, it certainly gives you a huge technical edge over others in all your interviews and career planning.

Hope this helps!!!
