It was meant to be informal however 30 mins in to what was a discovery turned into an interview. Although I was ready regardless I felt it was very unprofessional and the manager himself was quite odd. I was criticized and told i applied for the wrong role, however I felt strongly that if the company doesn't offer opportunity you can learn any role and master it. Previous interviews were more pleasant and professional. If you don't bring at least a portfolio and solid resume with work examples to the table you are wasting your time. It is standard at professional levels and higher.
