Can you tell me a little about yourself? More than facts, the hirer is looking for conciseness, confidence, enthusiasm. Talk about your career path, not your personal life.
Why do you want to work for this company? It sounds like they want to hear what you want--but they want to hear what you bring to them. And why you are a good match. Talk about your admiration for the company and how well the posting fits your skills.
What are your greatest strengths and weaknesses. Don't brag. Also only mention weaknesses you have overcome.
Why are you leaving your current job? Do not bash! Keep your grievances to yourself. Say you've gone as far as you can in that company, want more of a challenge, something like that.
If you got fired, be honest--but say even though you were sorry to lose your job, it provided a chance to find something where you could contribute more.
Relax. Be yourself. And do not just pull out these scripted replies.
