Fiix Software interview questions

Contacted by the hiring manager to set up an interview time, we both confirmed the time (midday on a Tuesday). When it came time for the interview she didn't show up, and didn't respond to her emails until 30 minutes later, when she said "thank you for submitting your application, I will pass this along to the hiring team." When I inquired as to what was going on (as we had clearly set up an interview) she ignored my question and pretended like nothing was wrong. Not only was this unprofessional, but I received no apology, or even recognition that they had done anything wrong. This was after I spent quite a bit of time, taken out of my very busy schedule as a student, preparing for the interview and waiting for her to respond to my email. Very unprofessional and rude.
