Redo Tech (UT) Software Engineer interview questions

Process was to build Othello in an hour and then if you pass that you get specific questions from the engineering team you're applying to or suited for. If they're satisfied with everything they make the offer on the spot. They didn't send me any preparation materials and then tried to reference those materials when I came in for my interview. The interviewer said it was common for them to mess up since they're changing their process and interviewing so many people. They entire building felt like a "coding" sweat shop and the culture sucked, and the one interaction I had with them was very negative in being forgotten.
