You're an old-skool developer on paper but every place you mentioned sounds more like an environment of younger developers. We don't know anything about you but you may or may not physically appear to fit with the culture for these places. For instance if you show up in a suit and a tie looking like, well, a programmer at a bank, the younger devs may not feel like they would have fun hanging with you for the whole 14 hours days that you'll be working. The management may see your experience, do the math and figure out your age, and assume that you're likely to grumble about working 180 hours per week, sleeping in the lounge and eating pizza in order to "change the world" with/for them.

Assuming you truly want to work in an environment of a fast-moving startup and all that entails... Perhaps try some A/B testing on your resume. Remove some of your experience and omit the years of graduation, etc so that it isn't obvious you've been working in the field for 15 years. For example, just list your iPhone accomplishments and your work with Python. Maybe even re-send it to the same places. My guess is that you'll get more interviews. Then when you show up make sure you don't shave, wear some skinny jeans and a plaid shirt, get some dark-rimmed glasses and put stickers of underground bands on your macbook. Optionally get some tattoos. I bet you'll have better luck.

Being fit into the culture is easily fixable — surely you don't go to Google interview wearing suit. I did the opposite once though.

A/B testing sound like an interesting idea to try, thanks.

As a dinosaur in this industry myself, it's a bizarre feeling when your skills suddenly becomes too much experience! It can be a positive though because you have the luxury of being selective with the skills you present and still be 100% truthful. I personally try to customize my resume for each job and leave out any parts that I don't think will be relevant for the interview.

Good luck!
