How do I even answer these interview questions to get me the job?

Interview questions seem so stupid and kind of pointless because anyone can lie. I dont know how to answer what is your bias i told them i dont even know or what makes you think you are better then anyone else applying or what was your salary at your last job. I do not like job interviews i have been doing so many lately its like one a week. Sone of them seem especially bad because they are asking how would your friends describe you. Or how are you at parties .
