Multiple of these incidents have happened to Sundar.
""What are you, press?," asked the Samsung representative. After being let in - Pichai was inquisitive about Samsung's new smart fridge. The profile reveals similar incidents happened multiple times over at CES."
"Even after looking at the name on his badge, the rep had no clue that this curious, friendly inquisitor was one of the most powerful people in technology. "
It sounds like a lot of these are just people being clueless who Sundar is, not necessarily biased to thinking "he's Indian, so he can't be one of the most powerful people in tech".
I don't know Sundar well enough to recognize him in the streets or at a press event if I haven't spoken to him first. Same goes for a lot of CEOs of various ethnicities.
I really doubt that it's the norm.
Look at the numbers not the anecdotes.
There are disproportionate number of Indian CEOs. It would have been impossible with racism and what not.
