The problem with Indians is that they don't tell you if they don't understand you and they go for the easiest solution to meet criteria without looking at the bigger picture, maintainability and possible future use. Too often the easiest solution, no matter the cost.

It's a cultural thing. Most Indians aren't gonna tell you if they have a problem. Most Latinos will. Most Europeans will.

If you just hire a manager that can speak both languages, you'll be fine.

And the Indian culture isn't worse, it's just that you don't know it and you need different types of standards/criteria for different people.
