hi,

see b.tech in computer science admission in calcutta university is based on wbjee score. the cse department is one of the best department. the faculty members are well experienced , fair ratio among students and teachers. lab facility and infrastructure is up to date. however placement is best for cse among other b.tech streams. the average placement package is 4-5 lpa.

some of the company name which visits the campus  is Allahabad Bank,  Axis Bank,  DenaBank,  haldia petrochemicals,  HDFC Bank , TCS.

last of all I should remind you that for a good placement and secure a job you must do work hard, computer science is updating day by day and you should learn technology or programming languages apart from your university syllabus to get chances in top tier 1 mncs.
