Favourables:
Job security is good. You wont be removed until you get 2 continuous D Band; Onsite (if you are lucky)

Unfavourables:
Salary - Okay. Cant compare the salary with product based companies. Rating/Hike - If you have a good relation (Politics, Any kind of licking etc etc) with your appraiser then you will be considered for A or B rating. Hike will be 6-8 in avg. 10% for outstanding. Team outing - I never heard this in my project. Other projects within TCS may have team outing. Workplace env - Don't feel like professional env. For every pick they look for cost cutting. This includes House keeping. RMG (Resource Management Group) team don't respect any junior level engineer. Engineer have to take any project what ever RMG team says. Client place - TCS employee who work at client place has very bad exp. No TCS HR/Manager will visit you for any reason. For every TCS work you need to apply leave and come to TCS office. Managers - For any request there wont be any immediate action. For example: If you ask your manager for N/W Dongle, saying i need to connect from home to work/support my project activity. Manager wont bother until for another 10 -15 remainders/requests. Same is applicable for team lunch/outing. Promises will remain as promise WBT trainings - Accessing WBT in TCS is like hell. Sometime even after successful completion of course, status wont be updated. You have to revisit the course for bad sake etc etc
