Hi before answering your question ,you have not mentioned whether you have any work experience or not .If you have a work experience I would advise you not to join in any of the above colleges ,rather you can prepare for CAT and get an admission in reputed Management institutions like IIM,XLRI .Because all the above 3 colleges have a great reputation only for their technical programs like(BE/ME/M.TECH),and not for their Management courses .I would advise you not to join in any of the above institutions since the exposure will be very less and also companies recruiting management students will not select the above colleges because they obviously prefer students from IIM’S ,XLRI,BIM (Grade A colleges for MBA)to Grade B colleges Like PSG or Anna
But if you have already decided to join and If you don’t have a work experience, going into these college would be a safe bet .With respect to placements, these colleges would place their students in some sales positions, Clerical/PO positions in Banks with average salary of 4.5-5.5 lacs per annum.(Few IT companies do come but they recruit very less students).Out of the 3 colleges I would suggest you to join PSG or Anna as they have their brand names.But try your best to crack CAT exams and join some colleges that are reputed for their MBA programs .Hope this helps. Happy learning and all the very best
