I have hired Indian Mandarin speakers before.

A lot of times Mandarin is needed as it is to communicate with Chinese clients easier as well.

Most of the time even if you try to use AI tools to decipher real time what people say in Mandarin real time, you'd not be able to decipher 100% and there might be communication issues that lead to stuff like Functional/Technical issues.

Expand your skillset. Don't just be too focused on thinking that all Employers hire just cause of Race.

I had hired local Malays/Chinese/Indians to deal with Indian customers too.

These Malays/Chinese/Indians were hired because they converse and write well in Hindu and did excellent analytical work for that Indian project. What's your point?

Most of them don't speak English or speak very bad English. Thus their primary usage of Mandarin.

Sorry. I meant Hindi.
