CTDI Test Engineer interview questions

I got stood up TWICE for a virtual interview with CDTI. The first time I was stood up I didn't even get an explanation or apology; I only took the second one because I am in need of employment only for the same thing to happen again. That should be an enormous red flag about this company for anyone looking into them, not only do they "forget" about you, but they also don't have the courtesy to even explain anything. Only rating the difficulty as very easy cause I have to put something there, and it's easy if I literally didn't have to do anything.
