Yes, you can easily choose IIM Ranchi or Trichy based on their placement statistics because the placement scenarios at both IIMs seem promising despite the lack of infrastructure and campus facilities. In many cases, Trichy and Ranchi have exchanged leads outside the ABC and LIK worlds. All can be overcome if you are taught by the best professors.

Elaborating further, IIM Trichy seems better than Ranchi or Rohtak to me. The reason being the superior teaching methods and its favorable location both for students as well as recruiters. Apart from Trichy, other IIMs are also doing fairly well compared to non-CAT MBA institutes. These are doing well with the help of sponsor IIMs which arrange faculty and placements. These in turn select their own Directors and invest in the infrastructure required in another 3–4 years as Trichy and Ranch have already done.
