IIT Mandi had only three branches. Civil branch started in 2016 only. Package and opportunities follows: CSE > ME >= EE. In the top companies we have Amazon, Microsoft, flipkart and all. in 2015 one student also got placed in Google. Placement of ME and EE students in core companies is not up to the mark. Average is 10-11 lac for CSE and 6-8 lac for EE and ME.
As being an IIT this college has a long list of recruiters offering good packages to students.Recently Flipkart offered 27L to the selected students.
Very reputed and renown companies come and select students for internship. Stipend offered by them is also irresistible and give students economic supports.
I graduated in 2014 and their was an economic slump in India. During that time very company visited our campus for Mech recruitment. Altair offered 7LPA, Trident 9LPA and LnT offered 3 LPA. Recently I got to know a lot of companies visited like M&M, Tata etc. for mech.
During my time we did not get much offers because of Economic Slowdown. One company offered me an internship(Polaris Financial Technology) but when I went there, they directly refused it. So I had to work for some relatives and they were a certified company.
In 2015, Amazon visited campus who picked 10 students (5 PO + 5 PPO) @27 lpa domestic offer. Others were Microsoft, cognizant, TCS, tata motors, Eclerx etc. The off-campus placement highest was around 1.7 crore in google. Placement occurs in 7th sem, almost all the students were placed.
Yes, you have to contact personally with professors. The professors are helpful, and liberal. The stipend may vary according to your work done. The companies for placement and internship are same. They pick for both positions. like Amazon, Microsoft etc
