AZZ interview questions

I received a call from HR who left a message to call her back regarding the Sales Manager role I applied for. I called back about an hour later and she thanked me for returning her call promptly. After introductions, she wanted me to walk her through my background. I began to give my experience and a couple minutes during the interview as I was walking through the power points of my experience matching the role I heard her talking to someone in the background. I stopped as I assumed she was talking to someone important. She said go ahead and continue. continued and shortly I heard her laughing. I thought, WTF?! Is this seriously their HR department? What a joke. So I quickly finished and she said she would send me an email and update me on the next steps. I was told they are bringing candidates in for in person interviews the first week of January. I never received an email nor did I ever hear back from this rude organization. The worst company I have ever interviewed with. Seriously, does this company have any talent if this is their HR department. Do yourself a favor, don't even apply to this joke of a company. They will likely assured go out of business. Thank you AZZ, as you lived up to your name!
