First of all, I would want to tell you that no college can guarantee you a placement abroad as this is totally dependent on the company decision, vacancy in the job location, projects going on in the location of your choice.
Hands during campus placements one cannot expect for job location of his or her choice, although your choice may be taken in consideration by the company where again the decision is on the company to place you in the location of your choice.
However, this is not the case at off campus placements where the company beforehand advertisers for the job and the location where they want to place you at.
Now, about National Institute of Technology Surathkal:
The closest information I can provide you with your query is that the International placement at the college got was around 45 lacs, particularly and the computer science branch.
I hope this helps.
Good luck and cheers!

Usually civil engineering students go for a masters degree or a Ph.D. program. Many of them get admits into various abroad universities. This is the trend I have mostly observed among my seniors. As per my knowledge very few core civil companies visit our college NITK, Surathkal. Some of them include L&T, BPCL (Bharat Petroleum Corporation Limited) and the pay offered by BPCL is really good considering the fact that it is a PSU and hence includes more benefits. Apart from these core companies data analytic profile and management profile are offered by various other companies. Quantiphi analytics, Thorogood, ZS Associates, i3 consulting and many more are open to civil students in NITK.
