Glassdoor interview questions

I had a phone screen with a recruiter, a 45 minute phone interview with the hiring manager and an onsite interview with 4 people plus the hiring manager. The interview scheduling process was seamless and everything ran on time. All of the people I met with were extremely NICE and easy to communicate with. They took time to answer my questions and give me an idea of what it is like to work at the company.

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.
