Glassdoor Associate Account Manager interview questions

I went through a typical phone screening, which then leads into a mock sales call where I had to work through a deck in 20 minutes to three employees over a conference call. From there I was invited into the Chicago office for a 30 minute interview with the VP of SMB Sales. When I arrived she told me that was a mistake and that I will actually be talking to three other employees as well. Up until the in-person interview, it was a very positive experience. The woman who was interviewing me started out with a brain teaser " Suppose you had eight identical balls. One of them is slightly heavier and you are given a balance scale. What's the fewest number of times you have to use the scale to find the heavier ball?" - or something similar. I had seen the question in the past so I knew the answer, and she got upset I knew it so quickly and proceeded to drill me about my SAT and ACT scores, and after telling her I got a 30 on my ACT she responded with "Is that even good"? We moved on by her asking me what questions I had for her to which I started with "tell me about your time at Glassdoor and how you got where you are", her response was "I'll turn that around on you, what do I do here"? After answering incorrectly she sat back and asked me if I even prepped for the interview and if I was wasting her time. Finally, after 20 more minutes of our interview, she stood up to leave so I stood and extended my hand, which she just looked at confused. So I asked if I will see her again, and she answers "Well, we'll see how you do". Three more employees in the position come around and have more conversational questions probably looking for a culture fit. Everyone else was lovely. They finally got back to me a few days later and I couldn't start for 3 months so the timing was off and they asked for me to reach back out when it was closer to when I could start. It was one of my first interviews straight out of college and honestly was the most humiliated and dejected I ever felt in the interview process. For a company that prides themselves on transparency, they should be more cognizant of how they treat job candidates.
