I agree not every fresher gets such salaries. The actual figure depends on the company. A company could be paying less to a fresher. Is 1500000 rupees or 2000000 rupees a good number for you? Then in the same company it is possible that there are people with 10+ years of experience who are earning 5% to 25% less than that.

But my 3000000 rupees example is not unusual. You can see madmax108's comment in https://news.ycombinator.com/item?id=18343962 where he was earning more than 3500000 without being from IIT in just 3.5 years of experience. Not a fresher exactly but when I had 9 years of experience I was earning less than that!

Also see https://news.ycombinator.com/item?id=18343659 where someone says fresher salaries of 60000 USD (4400000 INR). So I don't think my example is unusual.
