does PhD mark is calculated for candidates having PhD degree without NET/SLET in universities for the post of asst. professor?
See while you are applying for the Assistant Professor post, then the main thing that will be accounted your aptitude through the examination you give (College Service Commission/any examination for the post of Asst. Professor) & based on that only you will be called for Interview. Now in Interview, if one has good knowledge then all those marks & other things don't matter. What matters is the thesis & the knowledge the candidate have.
Now if the candidate is not upto the mark but if he/she have a good marks in PhD or in NET then sometimes the Interviewing Board can give some preference.
I hope this answer provides you some insight. Wish you a great day!
