DIC International interview questions

I was offered an interview by email. The company was slow to respond about my availability so I ended up having to take a half day off to do a Zoom interview from home. They canceled without telling me due to my visa expiring in June. It's January. It was a misunderstanding but they didn't try to clarify and didn't cancel in advance, they simply canceled on Zoom so that when I went to login, I couldn't access the link. Afterwards they told me why, so I told them I had made a typo on my application, but I had also already sent information regarding the visa in a previous email per their request. I sent a photo of the visa and asked if we could proceed with the interview. They called and said all this stuff about the position being uncertain and not wanting to waste my time or money. I told them I had already taken unpaid leave for the afternoon. They said it was difficult to have the interview and wouldn't budge. Seeing how they handled this situation, I wouldn't recommend them to anyone. They are unprofessional, disorganized, poor communicators, and will most like mistreat their employees.
