ZuluTrade interview questions

I had first interview with HR, after one month they contacted me for second interview, it went well so I was invited for third interview, on which was scheduled one week ahead. One hour befire the interview, I received rescheduling mail for after one week. Anyway, I attended the interview, which went great, and I was asked if I would like to meet the PM team on which I agreed. So several weeks later no sign from Zulutrade. It was really unprofessional to leave a candidate without even explanation or feedback at that point. Hope this happened only to me and other candidates are not treated like that.
