There's no worse feeling than when you're in an interview and the interviewer asks you a question to which you don't know the answer. 

The best way to handle this dreaded debacle is to go into the interview prepared. Familiarize yourself with a few common difficult questions and arm yourself with answers prepared ahead of time.

Check out these tough interview questions and some suggested responses in order to avoid an interview disaster:

Tough question No. 1: "Tell me about yourself." 

This is usually the opening question in an interview and it's the perfect moment for you to toot your own horn -- not to tell your life history. Your answers should be a quick rundown of your qualifications and experience. Talk about your education, work history, recent career experience and future goals. 

Suggested answer: "I graduated from University X and since then, I have been working in public relations with an agency where I have generated millions of PR hits for my clients. While I've enjoyed working on the agency side, I'm looking to expand my horizons and start doing PR for corporate companies such as this one." 

Tough question No. 2: "Why did you leave your last job?" 

This is your chance to talk about your experience and your career goals, not to badmouth a former boss or give a laundry list of reasons for your exit. Instead, focus on what you learned in your previous position and how you are ready to use those skills in a new position. 

Suggested answer: "The company just wasn't a good fit for my creativity, but I learned that organizations have distinct personalities just like people do. Now I know where I'll be a better fit."

Tough question No. 3: "Where do you see yourself in five years?" 

Let the employer know that you're stable and you want to be with this company for the long haul. Keep your aspirations to take over the firm with which you are interviewing, own your own company, retire at 40 or be married with five children to yourself. 

Suggested answer: "I want to secure a civil engineering position with a national firm that concentrates on retail development. Ideally, I would like to work for a young company, such as this one, so I can get in on the ground floor and take advantage of all the opportunities a growing firm has to offer."

Tough question No. 4: "What are your weaknesses?" 

The key to answering this age-old question is not to respond literally. Your future employer most likely won't care if your weak spot is that you can't cook, nor do they want to hear the generic responses, like you're "too detail oriented" or "work too hard." 

Respond to this query by identifying areas in your work where you can improve and figure out how they can be assets to a future employer. If you didn't have the opportunity to develop certain skills at your previous job, explain how eager you are to gain that skill in a new position.

Suggested answer: "In my last position, I wasn't able to develop my public-speaking skills. I'd really like to be able to work in a place that will help me get better at giving presentations and talking in front of others."

Tough question No. 5: "Why were you laid off?" 

This question will become more common as the economy continues to slow down. It's a tough question, however, especially because many workers aren't told exactly why they were laid off. The best way to tackle this question is to answer as honestly as possible. 

Suggested answer: "As I'm sure you're aware, the economy is tough right now and my company felt the effects of it. I was part of a large staff reduction and that's really all I know. I am confident, however, that it had nothing to do with my job performance, as exemplified by my accomplishments. For example..."
