Pros
Some projects are cutting edge. If you get into one, your future is good. Domains include DSP, Linux, TV, Mobile, Playstation, Sensors, Cloud, Hadoop, ML etc. Good opportunities for pursuing POCs outside project during Technical Events. Annual day event is good, mostly conducted outside Bangalore over a weekend. HR policies are good.
Cons
As always, some of the projects are of maintenance type. Most are service based and few are on the Sony's products. Depending on your client, your work pressure varies. But clients are typically hard working so you may need to keep up with them. But not that bad. Salary is pretty average, on the lines of service companies. Though you are given chance to participate in technical events, you will have to spend time outside of your project work. There is no 20% free time.
