Dear Student ,

It would be better , if you could elaborate your query more properly .

Well, As you have said that you have cleared GATE , So you have chances to get PSU jobs as per their recruitment process and eligible vacancies .Also some PSUs releases vacancies for specifically selected papers and stream like Electrical, Mechanical , Civil etc.

Some popular PSUs name are :

• ONGC
• IOCL
• BARC
• ISRO
• NTPC
• BHEL etc.

And , now your 2nd blurry query that , if you want to be a professor, then 1st you have to complete your M.Tech degree in your preferred Specialization , you can also opt M.Tech +Ph.d integrated for an advanced degree .
