Which is the best college in terms of placement in OPS/consulting/general management among IIM Raipur, Rohtak and Udaipur?

I am aware of the placement scenario at IIM Udaipur only as my sister recently graduated from it.

Operations

The faculty base of this domain specifically is very experienced and includes world class professors like Director Prof. Janat Shah. 

Apart from faculty, the club SKEIN conducts national level summits (SCM Summit) by inviting industry experts to enlighten the students.

Consulting

The consulting club ConsultU takes charge of providing live projects throughout the year for students.
