Doing Job is not necessary however it adds value to your profile and increases your chances at admission
Few good colleges require Job experience depending on mba programmes
Hence if you can you should do job for 2 years which is sufficient enough

Get registered with job portals like naukri, jobs assist, monster, shine etc. Read Employment News, leading national and regional dailies. Visit web portals of leading firms. Your personal contacts can be of assistance.

After BBA you can get job as Financial Analyst, Marketing Executive, HR Manager, HR Generalist, Operation Manager, Executive Assistant etc. But I suggest you to do Masters also to explore more possibilities.

You need to study MBA in HR.
