Typeform Digital CSM interview questions

Had 3 interviews and then a panel 'case study'. Obviously my interviews went progressively well however was told I was to have sent over the case study ahead of the panel interview, which was not stated in any conversation. In my 20+ years of work experience I've never been asked by any company for a presentation to be sent, especially that was not being compensated. It's imperative companies understand the time candidates invest in the process and to not dismiss a viable and qualified candidate based on the company's misdirection.
