Jadavpur University Kolkata Answered Questions

As per the information available on JU's website, Admission to undergraduate programmes in the FET is through the West Bengal Joint Entrance Examination, conducted by an independent body, followed by counseling. So the JEE Main scores are not applicable here. You have to participate and obtain a decent rank in WBJEE for getting admission here in B.Tech courses.

Hello Pradip, it's very nice to hear from you that you are interested in doing your ME albeit in evening classes. By this it looks likes that you are already working and desirous of obtaining this PG qualification. Right? It's surely a great idea. But unfortunately ready information is not available. I suggest you google about engineering colleges in your place of residence. Then ring up each college to know if they offer evening ME. If yes ask them for admission procedure.
Best wishes to you.

which companies will visit the campus of an engineering college is basically decided by the vibrancy of the placement cell of the college. If it is more vibrant then more companies will visit the campus. Unfortunately the data in this regard is very sketchy and unreliable. You can perhaps contact the alumni to find the status. Best wishes to you.
