Macdonald Realty interview questions

The interview was easy and people were super nice, however the HR team is extremely unprofessional. I am so disappointed in how they did even send a rejection letter or reply to any emails that they have moved onto the next candidate. The least you can do is tell me no I don't want you. That is HR's job. The people I met with were super kind and the process was fine until I received no response leaving me confused as to how I should proceed when they told me I would receive an answer. Unprofessional.
