Pros
I am writing something here only because of the word limit. It's up to reader whether they consider them as pros. 1. You may not write single line of code, but you do write lot of emails . So email writing speed improve. 2. Seating arrangement is good. 3. You will go through managerial insult on regular basis and occasional insulting from random customers. Over time you will gain significant capability to digest insult. 4. Congrats. You are no more an "Engineer". You can proudly introduce yourself as "Technician" (as customers often refer to you by that). 5. Some opportunity if you want to become consultant or customer relation. But you must stay away 100 miles apart from this company if you want to be a developer.
Cons
I am surprised to think how this call center manages to recruit IITians for a call center role for years and so far get away with it. They are indeed doing a great job by converting brilliant IITians to a call center executives. They probably have given you lot of false hope during campus placement, but let me give you what would you do exactly here. 1. You will search internet for random things you have never heard of(and don't want to hear it again), send document links, some suggestions like update the graphics driver or set some settings in matlab menu to customers. Some time you'd report customers about some bug. Mind it it's outside company policy to help customer technologically (ie. you cannot write code for customer or design their system). This is the role they call "challenging". 2. In campus recruitment they say support:project=1:1. In reality it's 7:3. Most of your time in project week would go to handle customers/calls from the last week. 3. No transparency in transfer. Not much significant positions in Bangalore. After 1.5-2 years, if you are lucky you get transfer in a QE(testing) role or some maintenance project which are very mediocre project. 4. People stuck here for years because they don't get opportunity in outside company. Most of the stuff you do here has no relevance in outside world. After couple of years even a service based company would not consider your resume, unless you want to join another customer care.
