CTO is most arrogant person I have ever met. Please go there and interview, you will start loving your current company. Though the task I have implemented was fine enough if one sees from iOS perspective. He wanted me to take different approach for the UI from product designing side. Which I believe should not be a criteria as I am applying for iOS Developer not product designer. He din't ask me any questions about my previous experience. When I asked him to at least have a review at the code and asked whether he was iOS Developer as he didn't introduced himself. His reply was - who do you think I am? I am CTO. So much arrogance and seemed like working there would have been really toxic. I have 4 offers right now and at least given 7-8 interview properly. This was the worst experience. Though I am not sure about other people at the company, from CTO side it seems weird.
