Hi,
In case of reputed government institutions (viz. NITs and IITs), Ph.D. is a must for getting shortlisted and eligible for the selection process for the post of Assistant Professor.
Some colleges also ask for experience, while others look at your curriculum and projects, others at research publications, research vision etc. Thus it varies from one college to another. But the process is not easy.

Hope this helps.
Wish you all the best!
