It's not that a shirt and tie is uncomfortable, it's that a t-shirt IS comfortable. If I can pick between two jobs where I sit at a desk all day in front of a keyboard, and only one requires a button-down shirt and a tie, the tie job can suck it.

Why would I volunteer for that? Additionally, I think in terms of tech jobs, especially in California, you'd actually have to go looking for a place that makes you wear a tie.

I don't think I've interviewed anywhere in my adult life that had a dress code other than 'you have to wear some kind of pants in the office'.

I once worked for a big company that had no formal dress code at all. I asked my manager about that, and he said the issue was dealt with case by case when someone complained about someone else's attire.

The only time I can remember it being an issue was when one guy wanted to go barefoot at work. The eventual decision was that going barefoot was out, but flip-flops were acceptable.
