Auth0 interview questions

I've done quite a few interviews in my time and this has to be the most disrespecful one. I think the hiring manager decided as soon as he saw me that I was not what he was looking for. As a solution engineer your job is not to give answers without first discovering the need base. He asked me a basic question on for a client who would want to choose between saml and OIDC what would I suggest. I asked more needs based questions and started taking about trade offs. Ultimately he said the right answer is OIDC not same and that no one uses saml. I've been working in the Identity space for years now and this is simply not true. Whole interview lasted less than 15 minutes. Super dismissive, no interest in my background. I honestly thought I was being punked because the level of disinterest was quite shocking.
