Pros
Work quality is great since company is in growing phase. A lot of things has to be done. You will always have some work to do. Cool colleagues to work with.
Cons
Salaries has a huge variance. There is no standardization done for it. If you don't negotiate well and didn't researched while accepting offer you might get into depression after few months knowing the fact how insanely your equivalent colleague is earning. Try bargaining in Lajpat Nagar while preparing for interviews, will help in negotiating the offer. People from IITs are considered massiha and are given significantly responsible positions. Especially lower IIT people with obscure branches are given title of some or other managerial position in the company. The kind of work they do has zero correlation with their undergraduate studies or them being an IITian.
