I'm also in a similar position, although I found that my experience of shipping SaaS and software largely on my own is completely ignored. Never mind the challenging software design decisions and the amount of unpaid work one must put in before it starts to make money (software is hard but that's because I'm an Economics major with no clue about engineering and only useless information about the stock market I'm supposed to be able to predict). Not to mention that I've actually worked as software developer at a company for 2 years because obviously what could a guy without a CS degree actually have done such as changing and influencing the company's product design and features?
None of it matters because I don't have a CS degree and apparently reciting algorithms and your ability to solve it in the shortest time possible is an absolute indicator of your ability to contribute to a tiny fraction of that company's product that is far less challenging than anything I've done by myself.
I've pretty much given up going to interviews and back to focusing what really matters, ship more software and get rich.
