Isn't the sample size too small for such generalizations?

The so-called "senior" guy just comes across as a bully. Nothing more. Nothing less.

It also indicates that the indian side did not have a good filtering system in place to keep such folks out.

It also shows that the project management was not quick to spot this trouble and try to correct the senior developer's behavioral issues.

But drawing conclusions about the culture of a billion plus people based on that seems a bit extreme.
