Tripadvisor Software Engineer interview questions

Very rude and condescending interviewer. Without any introduction, he just asked me to open a browser and type the collabedit link as he read it. And then after he finished describing the coding problem. I tried to have a conversation with him about different approaches and guess what, whenever I asked him about his opinion on an approach, he just threw one sentence back at me: 'what do YOU think?' After several back and forth I realized he had no wish talking to me at all so I just started scratching and trying to solve the problem on paper. And there was about TEN SILENT minutes without anyone talking at all!! So I solved the problem and described it to him, during the whole time he didn't even make one sound. And that was it. That was my very first tech phone interview and it was a disaster.
