Pournami,
I am also a fresh MBA graduate from Bangalore University, just joined the industry. I was in the same state as you are now when I had to do my internship. You can choose either HR, finance, or marketing. If you have chosen HR, get into the HR department of your selected organization (I did at MICO). Then, gather all the details about how the company is functioning, its products, etc., following the format provided by the university. Concentrate more on SWOT as your viva will be judged based on how you have done and how you present the SWOT analysis. This is practical; no one will see what topic you are working on. You can choose one area of study for your final project.
All the best! If you have any queries, feel free to email me or post your questions here.
