Allscripts Associate Software Developer interview questions

The interview process was pretty much the same as the other reviews on here. First one was an HR phone screen. The second interview was with the director of development and another manager. I was asked some basic questions about object oriented programming including access modifiers and other keywords. Talked a bit about multithreaded programming and what I was like outside of work. I got the notion that they actually cared about who I was as a person and my values. The third interview was conducted via Google hangouts. It was about an hour and a half total. There were several other people on the hangout. The director did most of the talking and asked most of the questions. I was asked about my interpretation of object oriented programming and what I thought the main points were. I was also asked about garbage collection in .NET, exception handling (try, catch, finally), and some data type questions. I was then sent a link to write code while all of the people on the hangout watched me. It was kind of nerve wracking. The first piece of code was to reverse a string. I solved it correctly, but they told me there was a much more efficient way of doing it. The second problem was to find the best seat in a row of seats represented as a boolean array. I did not feel comfortable completing the problem in the 5 minutes that they gave me. My normal routine is to create an algorithm and then develop the code after a suitable, efficient, and robust algorithm is created. I was told I could send the solution after the interview. I worked for another hour and a half after the interview and sent them my code. I got an email four days later telling me they could not offer me a position. After reading all of the same interview experiences on this website, I wonder if they are really hiring anyone, or just waiting for the "purple squirrel" candidates that are super experienced and just trying to find a position after a layoff or something. In the end, their spiel about hiring a person based on values and personality was just a bunch of talk.
