They sent me an assignment that was basically a complete marketing plan and they gave me 48 hours to send a presentation the day before the interview. The interview was already planned for the morning after and I was about to leave the house when i noticed a notification on my calendar: they cancelled the meeting with just a note stating that they looked at my presentation and they decided to delete the meeting because they prefer to move on with other candidates. The position was re-open the day after. I found everything absolutely unprofessional.
