which is more demanding Bee or b.tech for boys???

B.E. and B.Tech both are 4 year Undergraduate courses and are equally in Demand, subject to the Universities offering them. You perhaps cannot compare B.E. degree in Mechanical Engineering awarded by BITS Pilani to a B.Tech degree in Mechanical Engineering awarded by IIT Delhi. Both are analogous to each other and have similar aspects. However there lies a minor difference, which may or may not be a concern to the current Placement Freak Aspirants.

1. B.E. is a knowledge orientied course with greater focus on Theoretical aspects whereas, B.Tech is a Skill Oriented Courses with greater importance to Projects and Practicals in curriculum.

2. Universities offering B.E. degree usually also offer other Non Engineering Undergraduate Degrees like B.Com, B.Pharm, BBA, BCA, B.Sc., BA etc unlike Universities which offer B.Tech like IITs and NITs , having only authority to issue Engineering based Technical Degrees like B.Tech and B.Arch for Undergraduates.
