Exiger Sales Operations Associate interview questions

I will not be naming specific names, because I feel that's in bad form, but I am happy to share how the process shook out from my perspective: I applied for the position, received a callback from the Talent Acquisition contact to set up the second call, which was a video interview. Both interactions went extremely well by my reckoning, and I was told that I would be moving up to the third interview once the person in charge of the operation returned from vacation in about a week. That was over a month ago. I have sent follow up emails to both contacts and on LinkedIn to no avail. Exiger completely ghosted me. Total bummer, because my family and I were extremely excited about the situation. We went out to a fancy dinner in celebration after that second interview . I wish I knew what happened.
