Had first interview that seemed to go well and was asked to return for a second interview. For that there was a presentation for promoting a new product. Worked all weekend putting the presentation and graphics together, attended the interview and presented my ideas - and never heard from them again. No feedback given , never took my calls or responded to my emails. Completely ghosted me so can only assume there was no job and they wanted free marketing advice by pretending there was a job that didn't exist.
