Pros
1) There will be no restriction to work, you can explore your ideas and learn new technologies. 2) Seniors will be helpful, but you should have reach to them no one will come and spoon feed you. 3) If you survived in E2E for more than 3 - 4 month, you can survive in any other company. No time passer can survive here unless he is relative to the management. 4) Salary will be in time, only if any issue from the bank side will get delay. 5) For starting your carrier to learning new technology , my opinion good place.
Cons
1) Main problem here is no proper process is defined for any work. Process will keep on changing. 2) Multiple works will be dumped to single team due to lack of man power. 3) Life long you should be working in rotational shift. Peoples health doesn't matter. 4) You will not be appreciated for your hard-work , but you will get unwanted scolding even though the mistake which was not done by you. 5) If you stand for your rights, you will be kicked out of the company. (One of the coward move from the management). 6) If some employee report to there senior about his problem on difficulties in work environment , they will just confuse you and advice the things which can't be done rather than understanding it to help in solving the problem.
