My first band was founded by me, thus it didn't matter if I couldn't play, which I couldn't to be frank.
When I joined the band I'm in now (as per the opening post) I felt I was nowhere near good enough to join a signed band.....the audition probably confirmed that but it was who I was that mattered to the others, the fact that we clicked and got on instantly. The playing could be improved later, much much later in my case.
