Getting a job in San Francisco

  I will add than Twitter had a specific atmosphere compared  
  to other so called startups. The employees seem to be hired 
  on more than skills, everyone at their office is very much 
  hipster like, beautiful looking, feeling super confident 
  and ready to kick it. Walking around Twitter sometimes 
  almost feels like walking within a TV show.

>Mecca for Software Engineers, the only place in the World where the guy in front at Starbucks has big chance to be Software developer.

I'm a iOS developer and I love software, but this was one of my main reasons for leaving SF.

The way Fabien describes SF as a Mecca evokes the sense of wonder Woody Allen had about the City of Love:

You know, I sometimes think, how is anyone ever gonna come up with a book, or a painting, or a symphony, or a sculpture that can compete with a great city. You can't. Because you look around and every street, every boulevard, is its own special art form and when you think that in the cold, violent, meaningless universe that Paris exists, these lights, I mean come on, there's nothing happening on Jupiter or Neptune, but from way out in space you can see these lights, the cafés, people drinking and singing. For all we know, Paris is the hottest spot in the universe.

There's something nice about being in a city where everyone is one the same wavelength, but I think there's something more romantic about being holed up in a Parisian apartment that's stood the trial of centuries, committing to GitHub with the Eiffel Tower in the window (physical or otherwise) and such tremendous history all around you.

In all fairness that's not what he said. Some companies - like google - have a very objective hiring process based almost entirely on technical skill. But many other companies include "fit" as a part of the hiring decision. I haven't interviewed at twitter but I could believe they are like that.

I've thumbed down candidates who did well on the technical part of the interview because I felt I wouldn't get along with them day to day. Not as extreme as "beautiful" people who are "ready to kick it", but more like arrogance or social awkwardness.

I was really confused because an E3 is a visa very similar to a H1-B for Australians and an E1 is a visa for traders from countries that the US has a free trade agreement with.
