JIS College of Engineering

Yes ! All students of cse department get placed in good company

Yes, you can join through management quota.

I am not pursuing my B.Tech course from this college but I have been in touch with a senior and according to him the college is having an average placement of 30-35% for BCA and IT students. But the problem is that the packages which are offered by the companies are less. Infotech, Wipro, TCS and some more IT companies had visited the campus to offer the job.

Vel Tech is better than the other one. If you want to know why I am saying this, click on the link given below and watch the video till the end-

If your WBJEE rank is good, say below 15k then you can apply for JIS College of Engineering.

As per my knowledge there are some chances but it's tough to get BME in TWF with this rank. Try this link:

No, but don't know why JIS College's rank is so high in local newspaper ratings, may be it is paid promotion but from study point of view there are many other colleges which are better than JIS.

Yes, you can. Stream may vary.

If you are talking about CSE branch then it is the best branch in JIS as per my knowledge. If you get better than JIS you should get.
