Well, I have been working at here for around 1 year and 5 months.
Overall SI is a good company.

We have R&D team, and Application Support teams, most of our clients are insurance companies.

Most of the people here are very friendly, and I can say there is no office politics at all.

The benefits are OK, but we cannot claim OT. Most of the time you won't have to stay late, depending on which team you are in and client's request.
Increment on salary are quite good, depending on personal performance. On my first year, my leave is 18 days, now it is 20 days. The longer you stay here, more leaves and allowance you can get. you may also get travelling allowance if client requested you to travel to their side (Not too often).

For myself, I have joined both application support team and R&D team. Seniors, team leads, and managers are friendly and willing to teach. I've been doing quite a few projects and learnt a lots. If you really have passion in programming, you may try R&D team.
