IntelyCare Android Engineer interview questions

I was contacted by a recruiter I was working with, asking me if I was interested in a role at IntelyCare. I had a phone screen and passed that, we had a really good conversation about emerging mobile tech and some android specifics. I enjoyed talking to the person on the phone actively, so that was a breath of fresh air. I was invited to an on site interview. The interview was...weird to say the least. Nothing like the conversation I had on the phone. No one was really prepared and all seemed to be unaware they were scheduled to interview me, so there was an awkward wait in between each interview while they were tracked down. Red flag #1. I interviewed with 5-6 people, all with different roles, as is typical. The interview was in a dimly lit, unfinished room at a round table. Red flag #2. The rest of the office looked great so I just figured they were expanding and it was a good, fairly private place with a door to interview. But I wasn't feeling great about the role at this point. I was looking for something with a strong developer community and didn't feel that here. One of the technical interviewers joked about never leaving the office and how rewarding that was. Red flag #3. The real strange part came in my interview with someone from leadership. He was unfriendly and condescending. When I said I was looking for a company with a community of developers I can learn from, he asked how I got my degree, implying I didn't know anything and was asking to be trained and didn't know how to do the job. I am not an entry level candidate so that was weird. The interviews had gone pretty well from my perspective until then (as in, I did well), he seemed to want to find something wrong with me as a candidate. I regretted not walking out of the interview sooner, as it was definitely a waste of time at this point. Red flag #4. He asked a very low level Java question (not sure how it was relevant to android - we're talking direct memory management here), then just left the room, stopping me from asking any questions about the problem. I am very experienced interviewing and this is far from typical. I was just left with a pencil and piece of paper, not even an IDE. It was about 5:20pm by then (They took longer than the scheduled 5 pm end time...) and I heard him yelling at an employee over the phone about having left the office, right outside the cracked-open door. He kept coming in and saying "just a couple of minutes" and sounded irritated even though I hadn't asked how much longer. Red flag #5! I contacted them over email after thinking about what just happened and told them the role was not for me that night. Bummer because the phone screen was a really good experience. The rest was downright hostile.
