GATE 2022 PSUs
I am a 30 year old guy without any job and work experience. I was very casual and lazy. I am 2013 passout in Btech Electrical Engg. This year I have prepared really hard for GATE 2022. But only one thing I am getting worried is about the PSUs interview. Will the PSUs reject me straightforward ? I have no justification for my 9 year gap.
