No.. but it is a tribe, "are you one of us" e.g. white boarding + algorithm/data structures. You may have better luck at slightly larger companies that are past the startup phase. Buy a whiteboard and have some (CS) friends over, practice. My experience has been that "experience" doesn't matter as much as the fundamentals do and being a nice reasonable person. The experience and degree get you the interview... the fundamentals land the job.

When explaining your accomplishments, put them in context they can understand. This isn't technical specific (unless shared) but rather at the more abstract (business) level.

There's the interview kickstart guy on here too. He runs a course that gets you in shape. You get interviewed by employees at the big companies which can only help. Triplebyte here also does a pre-screen for YC companies.

Good luck!
