I did 2 interviews of 1 hour each with both of the managers, plus a 3 round interview with both of them in which I had to prepare a case study and a presentation. They were happy with me and wanted to offer the position. I accepted it and signed a contract of 20 hours per week. After 3 hours of signing it, they tell me that it wasn´t valid anymore cause I was explained that it was only 6h/week. How works only 6hours per week? Where is the joke? Totally not serious enterprise. It is not serious neither fair to make someone 3 round interviews and prepare a case study + present it for a position of 6 hours a week. Ridicoulous
