This interview was a paired coding exercise over the phone. This stands out as the worst interview experience of my search. The question involved rotating matrix elements by plus or minus 90, 180, or 270 degrees. (Not creating a rotation matrix, but physically rotating the elements.) There was an emphasis on an in-place solution. The interviewer basically mislead me on two occasions while talking through the solution. I was working out the mapping from (i, j) elements to their new (i', j') location, which basically requires looking at examples and intuiting the right mapping. I wrote down a formula with a mistake in one of the equations, and the interviewer said something like, "I see, that makes sense, go for it." Later, she said that she was just acknowledging my progress, and it wasn't her responsibility to guide an interviewee. This misstep wasted a lot of time. I did fix it later and get a correct implementation, but the solution wasn't in-place. The interviewer also discouraged me from adding Python doctests, which would have been quite helpful. After the interview ended, I felt I had made a creditable pass at the problem, but I was so frustrated with the experience that I didn't want to proceed further with Akuna Capital.
