LNCT Bhopal is a better option. When appearing for the placement interview from BIT Jaipur, you will have to compete with students in a large number as pooled placement takes place and students from all the BIT are allowed to appear for that. 

While LNCT offers good placements. According to the recent highlights, the average CTC offered is 3-8 LPA. In 2020 Microsoft offered the highest CTC of 27 LPA. 

On the other hand, if you are comparing BITS Pilani and LNCT Bhopal then without any second thoughts, Pilani is the answer. In order to get admission there, you should be able to crack their entrance exam (BITSAT) and it takes great effort.
