why indian companies are not providing good salary.why they are taking recession as a backbone .

You need to look at a broader perspective - recession means a lot more than costing it also involves low customer confidence in signing new projects, delayed payments, existing projects are put on a slow phase, getting funding for companies is much more difficult. All this makes a company adopt a cautious approach in taking new resources on board unless its is very critical to their operation. Even though the US and European markets are on a recovery mode the actual translation to revenue for indian companies will take at least another 1-2 quarters.

this is  really a recession time
