What advantage do I get in L&T if I complete NICMAR?

I am assuming you are asking about L&T Constructions Pvt Ltd. Wo when you go to corporate, your skills and knowledge matter more than the fact that from where you pursued your MBA. 

But there are some advantages that you can take out if you want to work at L&T. It offers placements to NICMAR students, and they offer a position of post-graduate engineering trainee in the beginning. It is a mid-level management position. 

The salary offered ranges from about 6 - 7 lac per annum, but it keeps on increasing as the inflation rate rises in the country. Apart from this profile, L&T does hire for other profiles as well, like execution contracts and planning.
