Two back-to-back phone interviews. I was free to use my language of choice. First interviewer asked me a generic question about my experience with projects. Then a steady stream of technical questions. -Write code for the 2-sum problem -Design deck of playing cards and some of its functions Second interviewer sounded tired and disinterested, and did not offer any hints when I was struggling with his (unreasonable, in my opinion) questions. They were too complex to write complete and efficient code for, under pressure and in a short time limit. But they would make good high-level / design questions instead. He also asked me the same generic question about my projects.
