Hey Aspirant,

Hope you are doing great,

As you want to know the eligibility criteria for the PSU. You cannot get a job in PSU just by qualifying GATE. You need to clear the cut off set up by the PSU to receive an interview call. You have to do well in the interview.

For information about the PSU recruitment through GATE:

For the eligibility criteria for admission in MTech from IIT. A master's degree in the relevant subject or a bachelor's degree in engineering or science (4 year program) or a master's degree in sciences or in an allied field of HSS with marks/CPI not below the specified minimum. The candidate either must have a valid GATE score or must have qualified JRF/NET.

I hope this will help you,

Best of Luck :)
