Dexcom interview questions

Do take home coding challenge first which involved building a sample iOS application using multiple libraries. Then technical + behavioural interview. Asked questions regarding iOS development and personal work experiences.

First round was smooth. I was asked about my experience and some behavioral questions. Second round was panel with multiple people but separately of 30 min each. All of them seemed they had already made a decision and didn't seem interested to know about me. One of them was in a hurry and would stop me in between while I was answering and would just move on to next question without me even completing my answer. If you dont want to hire anyone then why waste their time and efforts because if one is appearing for interview then they are looking forward to it.
