This is a great post, but I'm confused about your math in the first sentence. Maybe I misunderstand: 3 lakhs means 300,000 INR. If 720 INR per hour, that means 415 hours per month. If we estimate 4.5 weeks per month, that is 90+ hours per week! Where did I go wrong here? And there is no way Boeing is paying less than 20 USD per hour in India for people writing flight control software!

For other readers, if the monthly salary is 300,000 INR, that would be 3.6M INR per year, or about 45K USD @ 80 INR/USD.
