Placements at MITSOB for HR is considerably good. Full assistance is provided to all the students for placements. Highest package offered to a student for current batch is 7.8 lpa and average package reaches upto 4.5 lpa.
Fees for the 2016-18 batch is 6.5 lakh which which is payable in 5 instalments over 2 years.

At this score, no good college is permitted. My suggestion would be score well above 95 percentile to get good college and Lucrative career, else you will land up with very average career.

Placements are not great and doesn't guarantee 100% assistance, brand wise ranked far below in top 100 list. BIMM, Flame, Indira and PUMBA are better premium options you should consider.
