The eligibility criteria for the GATE exam is Engineering Graduate, while the candidate who has done post-graduate work can appear for CSIR NET (JRF). The syllabus for the GATE exam is less as compared to the CSIR NET exam, and in the GATE exam, we don't have a general studies paper. The GATE exam has a much higher difficulty level than the NET exam. The GATE exam is conducted once a year while the NET exam is conducted twice a year. The GATE score is valid for 3 years, and a candidate can appear for the exam any number of times. There is no age limit for the GATE exam, but if you are preparing for the PSU exam, there is an age limit. The NET-JRF (Junior Research Fellowship) score is valid for 2 years and can be extended for 3 years for SRF (Senior Research Fellow). The age limit for the CSIR NET exam is 28 (relaxation for OBC, SC, and ST as per rule). Qualifying for CSIR NET doesn't guarantee admission to any specific university. The candidate has to appear for the interview.

GATE is not an essential qualification for ISRO recruitment, but a good GATE score will boost your confidence, and the strategy of your GATE preparation will help you to crack the ISRO written exam and interview. The following options are open for young aspirants to become scientists or engineers at ISRO:
If you get into the old IITs (through a good GATE score), ISRO conducts a direct placement interview. If your rank is low, you can be admitted to IIST (for B.Tech candidates only, through JEE marks). This institute is meant to create active minds in the field of aerospace or avionics. You will be assigned ISRO (CGPA is the criterion). If you are not on the above-mentioned lists, then you have to reappear in one more competitive exam after your graduation, I. e. , the ICRB (ISRO Centralized Recruitment Board). If you do not pass the ICRB exam, continue your education. ISRO conducts direct interview-based entries for M.Tech. These are the options; now you can plan accordingly. I hope this will help you.
