Equifax Automation QA Engineer interview questions

I was approached on linkedin by Equifax's talent acquisition about interviewing for the role as my experience matched their requirements. I was told their colleague would be calling me to discuss the role and to expect a call a few days later at an exact time. On the day I messaged to confirm the call was going ahead and received no response, followed by the call itself not taking place. Two days later I received an apology as they had been in a meeting and asked if I could take a call that day to which I said yes. That call was then cancelled barely an hour before it was to take place, and a call was arranged for the middle of the next week. Again on the day I sent a follow up message to ask if it would go ahead, I received no call again, and no answer to my message after that. Without a doubt the most unprofessional setup I've encountered in all my time interviewing. This back and forth above took place across 3 weeks and still managed to not even get past a role overview call, a length that most companies would have their entire hiring process completed in.
