Our company recently recruited multiple Indian colleagues. Then we realize that "paid professional certificate" is the root cause of everything. They don't have basic technical knowledge yet hold professional certificate. They don't understand any Linux commands and have not much network knowledge.

Be initiative, give suggestions based on your professional knowledge. *my opinion might be biased because of the Indians colleagues that I'm dealing with
