It was setup as a phone call and shared screen interface between me and interviewer. When he call started the interviewer was unsure as to which language to use. When describing the problem he provided very little information. As we worked through the problem he changed the data description to ensure that my checks were invalid. He seemed rushed and put off by " the new system that he was using to keep notes in". he did not allow me to complete this , but instead moved on to next question. He did not seem to be prepared to talk about the database aspect at all.
