Blue Origin interview questions

I applied for the Avionics Software Engineer position for new graduates. In two weeks, I conducted a 30-minute phone interview with someone from HR. I then scheduled to do a one hour technical phone interview with one of the engineers at the company. In the first half of the technical interview, I was supposed to write a simple program in C++, and in the second half, the interviewer asked a couple of technical and behavioral questions and also allowed me to ask a couple of questions about the company. Three weeks after the interview, I was notified that they decided to not move forward with the interview process.

This was one of the more bizarre interview experiences I've had. I applied and had someone reach out for a phone screen. Thirty minutes into our phone call she tells me she needs to go because she didn't schedule enough time but wants to continue our conversation so asked if she could call me back in two hours. I said yes. Two hours comes and goes and I wait but no phone call. The next day, I receive an email saying sorry but something had come up so she couldn't call me back but wanted to know my availability for the next day. So I respond with my availability and ask if that time works for her. She never responded. Two weeks later I received an email that I wasn't the right fit for the job. It was unprofessional to say the least. I am a recruiter myself and interviewing with a recruiter for a recruiter job. I was pretty amazed at the lack of care for candidate experience.
