Kate Spade New York Assistant Store Leader interview questions

applied online, got the first interview, it was most technical sales questions, got the second interview it was the same questions, the second interviewer told me that the first interviewer "definitely" gonna call me back for further steps, she said today or tomorrow or the other day! they didn't call me back I followed up with email, they didn't answered and since they told me they definitly gonna call back I decliened another job and I went to shop to see the manager for follow up she said yes we choose to go with another candidate, the way they ghosted me was very unprofessional, they could have just emailed me Or answered my emails or maybe didn't tell me they definitely gonna took further steps. very disappointing and unprofessional.
