While an M.Tech is usually a requirement, the AICTE mandates a Ph.D. for Assistant Professor positions in most cases. While AMIE might be considered equivalent to a B.E./B.Tech in some contexts, it doesn't replace the doctoral requirement for Assistant Professor eligibility as per AICTE guidelines. Some institutions *might* have exceptions or relaxations, but these are rare and highly dependent on the specific institution and its needs.
Therefore, to be eligible for an Assistant Professor position, you generally need a Ph.D. An AMIE and M.Tech combination will likely only make you eligible for teaching positions at a lower level.
