Hello aspirant,

One of the way to get ino Public Sector Undertaking (PSU) jobs is Graduate Aptitude Test in Engineering (GATE).

In GATE exam candidates must have passed Graduation in Bachelor's or Master's in relevant field from a recognised Board.

There is no age limit for appearing for GATE exam. So, you can appear for GATE exam.

The point is that in interview you have to face the question why gap of 7 years and you must be prepared well for this question before itself with valid reason.

If you can crack GATE exam then you'll be eligible for PSUs if you meet the eligibility criteria.
