Intrepid Pursuits interview questions

I started with a two phone screenings, one with HR and one with a user experience designer. This phone screening led to an in person interview with multiple designers and HR employees. The last stage interview was three hours long including breaks.

By far, the most unprofessional interviewing experience I've ever encountered. The first point of contact was with HR. The coordinator of their apprenticeship program. She was no-call, no-show for 30mins, then when I reached out with an email, wasn't the slightest bit apologetic and just said she was on another call and will reschedule. After a couple of weeks went by and no response to my email, I figured they weren't interested. Then, I received an email from her assistant to pick a day to reschedule. After the screening with the apprenticeship coordinator, I moved on to phone interview. There were technical difficulties on their end because they had just changed systems and they needed to reschedule. Again, the same process of no communication and no reply to my emails and then weeks later a get a calendar invite. After doing well on phone interview, I was flown out to Houston to meet the team. I was told I was great at everything except this system design question that the interviewer himself did not no how to answer. I actually went through the interview process twice with them. Same results and they kept telling me to try again because I'm so close. After the second time, I realized that this isn't the type of company I want to work for anyway. If the way I was treated is any indication of how they treat their employees, then I'm good, thanks.
