It's true that Sasken is also similarly cheap. About a year back their MD/CEO gave an interview saying that they're aiming to be a $ billion company.
But my understanding is that telco businesses are really bleeding....also something about Sasken's accounting 1-2 years back......
Sasken actually used to do great quality work about 10 years back...now they've lost their cream....i read somewhere that their attrition is about 33%.
