Why most of the students are going for MBA after B.Tech?

You will get to learn about business communication, business intelligence, human resource management, enterprise management, time management, and much more. Thus, an MBA degree after B.Tech will equip you with both technical and business management skills, thereby helping you scale the corporate lad

Because they are under the illusion that:- 1) MBA is for fresh graduates; and 2) MBA can yield them better jobs just with the degree. Hope this helps. Thanks.
