The Usual Dilemma

Every MBA aspirant has quite many doubts regarding how to build up their profile and what will be best for their career. This group is to connect such people with others who can provide their insights and help them shape their future in the best manner possible.

I am a final year CSE student. 

I am a bit confused about if I should go for MBA in Marketing or HR.

Can anybody guide me (exercises, tasks, reading articles) about how to be exactly sure which stream I want to pursue?

 I have a PhD in biochemistry and I have worked in vaccine research for 4 years. I'm considering career switch to management role in industry.  I'm 35 years and thinking of doing a MBA from India. Should I go for regular or part time MBA? Also I'm want to know if MBA is the right thing for me now. Thanks in advance ?
