That is completely false.

I know who Vint Cerf is. One of my friends met Vint Cerf at Google, and I hope you see the irony in citing Vint Cerf. Vint Cerf is viewed within Google as a highly eccentric (aka weird), albeit brilliant, individual. If you come in looking like Vint Cerf for a standard engineering interview, you will look very weird and out of place.

A suit, even a well-tailored, modern cut suit, will be very weird in a software interview at Google.

Don't believe me? Spend a few hours at Google's Mountain View office to get a (admittedly superficial) sense of the culture there.

What I said about Google applies to other SV tech firms (or the SV offices of tech firms not based in SV).
