Devoteam Software Engineer interview questions

Interview with hr was really friendly and cool, but some of the business manager of the company are really unethical because if they don't want you they will just find a excuse to get rid of you and never say a word to you again. (attention, just some business manager. There are others that are direct and honest) One thing that happened to me: I get contacted by one of business manager, he say I was going to have a interview with a client. Some hours later a received a message saying that the interview is going to be delayed to next days and I never received any information again..
