Hey!

As per my knowledge Btech is more demanding than Bsc as it not only gives you theoretical knowledge about the subject but also gives a practical experience of how to apply the knowledge in real life. And then you can do M.tech if you have god interest in any research topic. Otherwise you can directly go for MBA to enhance your business and management skills. Also, a work experience of 1-2 years before MBA gives a good opportunity to grab a good placement as you have work experience already.

Hope I answered your query, thankyou!
