Hi Archana,
It' strue that B'lore cos. pay more then Pune companies. I feel that living costs are bit cheaper in Pune and since competition is less (far less MNCs then B'lore and good supply of talent through good colleges), they tend to pay less.
But you do have companies like Symantec, BMC , T-Systems, Triple Point Tech. which are known to be good paymasters.
