sir, I m getting about 69 marks civil, morning session, OBC cat.,final year student at NIT Uttarakhand, which PSU or college should i expect

Chances are good to get recruited in PSUs hope you have applied for the PSUs which are already done with their application form as per your eligibility. So to make it more specific for you, below I am providing Gate/PSUs College predictor, which you can use to know where all you have recruitment and admission chances -
