I applied online and had a phone interview scheduled. After passing that, I was given a coding exercise. From there, I was invited to the onsite interview, which was about 3 hours long. I interviewed with the realestate.com team. Most of the interview process was pleasant. The people I would be working with asked me questions that were related to the job itself and I was able to successfully answer their technical and white boarding problems. However, my interview with the software development manager was very disappointing. I signed an NDA, so I won't divulge the question he asked me, however, it's been posted by others here. I was given 30 minutes and a white board. After giving me the question, the manager left the room. I had a question about 5 minutes into working on it, yet I had no idea where I could find him. He didn't give me a way to contact him in the event I got stuck. He came back to the room after 15 minutes to check on me, which I then asked my question. He then left the room again. I had another question, yet he didn't come back for another 10-15 minutes. At that point, the time was up and I didn't have a complete solution. I would have made further progress had he been in the room the entire time and able to answer my questions like the other interviewers. I told him my thought process on how I'd finish the remainder of it, but he was visibly disappointed. I found this particular interview to be incredibly unprofessional. I was treated like my time and concerns didn't matter and I was set up to fail. This one interview left a bad taste in my mouth.
