GC America interview questions

Applied for this position 07/23/2025, rec'd email from HR manager to schedule phone interview. I replied within 15 minutes of receiving the email and we had an email exchanging culminating in the scheduling of a phone interview on 07/31/2025 @ 10:30 AM. Cool. I'm prepared, I'm excited, I'm waiting for the call. The appointment time comes, no call. I wait 5 minutes...10 minutes...15...20...25...30 minutes pass, nothing. So, I emailed her @ 11:04 AM, and asked if she was having difficulties and needed to reschedule. She responds at 2:56 PM claiming that the number she called was busy. I replied @ 3:02 PM and note the oddness of that, attempted to confirm that she dialed the correct number (and provided mine again even though it was on my resume), and no response. I follow up again on 08/04 @ 12:05 PM inquiring about rescheduling, no response. I follow up again on 08/14 @ 5:25 PM, and, you guessed it, no response. I checked to see if the listing was still on the site each time, and it was. Today (08/20), I checked the website and I see that the listing has been removed, so it has either been filled or cancelled. Either way, the discourteousness is astounding. And I really want to message the Sr. HR Manager or CHRO on LinkedIn and tell them about my experience. But, I am sure it will just disappear into the ether if I do, and I might run the risk of burning professional bridges before I can build them. Nonetheless, this whole experience has just left me super demoralized, and reading the reviews of this company here has just solidified that I dodged a MAJOR bullet.
