SewerVUE Technology Software Developer interview questions

First had a phone interview it went well, then a in person interview which also went well. Got called in for a second interview which went terrible, the interviewer (different person than the first) was disrespectful and frankly didn't even know how software works. I was asked questions like how long it would take for an algorithm to run rather than asking about the big o of the function. When I responded that I didn't know and needed more information he sent me to speak to the other employees downstairs and called me back up to ask the same question. I responded with my same answer and then took a guess which he responded very rudely: "Do you think I would hire someone if it would take that long? Then he started asking me generic interview questions from a paper and didn't engage at all. I honestly should of just left, it was one of my most terrible interviews. After looking at their review on indeed I realized other people has similar experiences. So highly recommend NOT applying here!!!
