Can someone kindly help me in preparing the right questions that I need to ask the iPhone developers at the time of interview? I have been looking out to hire the best and most professional iPhone application developers in Dubai and I had finalized one but I want to have a proper interview session with them first so that I can validate few of their traits that wouldn’t cost me any trouble later on in the future. I want the work to be delivered on time and also want to be sure of their work quality. Can someone help me out how to adequately ask them the right queries?
