It’s not entirely true that IIM Indore has a hard time getting everyone placed. Yes, it does take longer to wrap up the placement as compared to other reputed B-Schools like SP Jain, NITIE, IIMK, etc.
One of my friends recently graduated from IIM Indore and according to her, the final placements for 2020, took nearly 2 months to complete. While the other B-Schools wrapped up placements in 1 to 1.5 weeks. This delay in placement has nothing to do with the quality of education at the institute. It is due to the large batch size.
But at IIM Indore almost every student gets placed in a decent job. It doesn't guarantee you that the job or the salary will satisfy you. You will have to work even harder and polish your skills more to secure your dream job.
