I was invited to an interview and asked to use the slef-scheduling tool, I accidentally clicked the wrong date and there was no option to change it so I emailed asking if it could be changed but if not no problem I would move stuff around for it. It gets to my interview slot and I have still been given no more info other than the time of the meeting. My interview is at 11am, just past 11 I was emailed asking what my availability was like for the rest of the week. I said I can do it now or in the mornings for the rest of that week. Then nothing, absolute radio silence, I have emailed following up but still have heard nothing. They have completely wasted my time.
