After 6 months of interviews in the Bay, I gave up (due to cost) and decided to try another market... less than 6 weeks and I had a job in Charlotte. I had my first iOS role at a startup another 6 months after that. Even after the startup coughed me up (thanks again Zomato), I was able to get another iOS job in a month. I won't mention (any other) names but I can say that the culture fit issue doesn't really exist outside the Bay.
And to any decision makers out there, you are making a mistake if you assume someone like me can't fit on a team of 18-30 y/o. I fit in so well, in fact, that almost all of my new connections on LinkedIn are these same 18-30 y/o. I have made more friends with interns than I did when I was the age to intern. And my 20 year-old friends have no fear in making fun of my age just as I have no fear in making fun of theirs. We even talk sH$@! about race (oh yeah, I'm also black).
The experience has been awesome for me as well as them (I believe). So, the next time you have a chance to hire an old dev who just wants to be a fu$!@E~!! DEV - just hire her.
