Hi aspirant

If you really want to become a CEO of any company you need a lot of work experience in that particular company.You can take some examples like

Sunder Pichai ,CEO of google has joined GOOGLE in the year 2004 and became CEO in 2015.

Yes he is an engineer.

Indira Nooyi joined pepsico in 1994 and became CEO in 2001.She is not an engineer.

So the important thing is you can do any kind of course ,take degree start doing job and remain determined throughout your work.Someday you will definately get what you are wishing.

Definately you can do B.Tech and if you are not interested in it then you can do other bachelor degree.

Hope this was helpful.
