This facebook post by the English Press Club, BITS Pilani’s newsletter – The Fine Print should give you a very good (and quantifiable) idea about placements at BITS Pilani, Pilani campus.
Please note that these statistics are only for first semester of academic year 2014–15. These things vary with the market condition of the industry in question. And I think the statistics do not consider any off campus jobs which a student might have acquired without the help of the placement unit (or the university in general).
If you are joining BITS, don’t worry. Almost everyone I know who went to BITS is doing very good in his/her life. That doesn’t always mean earning 12 lakhs per year. You will be fine. 🙂
