HealthGraph India Ruby On Rails Developer interview questions

They gave an assignment to complete before having face to face interview. The assignment was easy but time consuming and after two weeks I completed the assignment got a call from the cto for further face to face discussions! But I must say one of the developers was very arrogant while taking the interview it was like he use to laugh whenever there was a question which I was not able to answer and this is really disrespectful and also he laughed at certain points which I wrote in my resume! they asked silly questions which developers can google and see and dont have to remember !!!
