Better still, you need a good ending. If your previous company took your advice and ended up going bankrupt, that's not such a great example either. Be prepared with a story about an idea of yours that was taken from idea to implementation, and considered successful. Pls check out the fanpage: Have you ever had a conflict with a boss or professor? How was it resolved? Note that if you say no, most interviewers will keep drilling deeper to find a conflict.

The key is how you behaviourally reacted to conflict and what you did to resolve it. For example: Never major ones, but there have been disagreements that needed to be resolved. For example. What do you know about us? Follow these three easy research tips before your next job interview: At a minimum, you should include the following in your answer: What type of product or service the company sells 2.

How long the company has been in business 3. Tell me what you know about this company? Do your homework before you go to any interview. Whether it's being the VP of marketing or the mailroom clerk, you should know about the company or business you're going to work for. Has this company been in the news lately? Who are the people in the company you should know about? Do the background work, it will make you stand out as someone who comes prepared, and is genuinely interested in the company and the job.

If your previous co-workers were here, what would they say about you? Ok, this is not the time for full disclosure. If some people from your past are going to say you're a boring A-hole, you don't need to bring that up.

Stay positive, always, and maybe have a few specific quotes in mind. What did you like or dislike about your previous job? What you liked - and what you didn't like - about your last job or the company you worked for is an indicator of how you might feel about this position if you were to be hired. Be careful what you say when you're interviewing for a role similar to your last one.

It's important to be positive and enthusiastic about the job for which you're being considered. What major challenges and problems did you face?

How did you handle them? With this question, the interviewer is trying to understand how you handle issues and problems. Can you figure out solutions and workarounds when there is a problem? How adept are you at problem-solving? Do you enjoy a challenge, or do you get nervous when there's a glitch? How are you when you're working under pressure?

If you fall for this one you shouldn't be hired anyway.

The interviewer is testing you to see if you'll speak badly about your previous supervisor. Simply answer this question with extreme tact, diplomacy and if necessary, a big fat loss of memory. In short, you've never had any issues.

Describe your dream job? Three words describe how you should answer this question: Relevance, relevance, relevance. But that doesn't mean you have to make up an answer. You can learn something from every job. You can develop skills in every job. Work backwards: Identify things about the job you're interviewing for that will help you if you do someday land your dream job, and then describe how those things apply to what you hope to someday do.

And don't be afraid to admit that you might someday move on, whether to another company or -- better job -- to start your own business. Employers no longer expect "forever" employees. Describe your management style? Try to avoid labels. Some of the more common labels, like progressive, salesman or consensus, can have several meanings or descriptions depending on which management expert you listen to.

The situational style is safe, because it says you will manage according to the Situation, instead of one size fits all. What have you learned from mistakes on the job?? Here you have to come up with something or you strain credibility. Make it small, well intentioned mistake with a positive lesson learned.

An example would be working too far ahead of colleagues on a project and thus throwing coordination off. What types of people do you find it difficult to get on with? In these situations, I find that by developing a good rapport the person, letting them know how important their contribution is to getting the job done, and appealing to their better nature………things get done.

I can organize my work very effectively. What are the most difficult decisions to make? This is one of the most typical behavioral questions in an interview.

With this question, the interviewer is planning to examine your behaviors under a problem and how you handle it. You may answer as sincerely as you wish, but there is one tip that you should notice: The key is learning. Then, tell the interviewer how you did resolve it or acted under such situation. Remember to keep a positive tone for example, when you talked about those who had made mistakes and be specific about details of your solution.

Finally, tell the interviewer of what you have learn from such experience. You may even scan your memory for many problems and consider them as challenges and how you resolved them in a professional manner.

Describe a typical work week? Hearing the answer and the interviewer may have an overview about you and your performance at work. So, it is very useful to look at this question beforehand if you have stated some related experience in your CV as to the current job. You may talk about what happened with your behavior or skills at work, such as the times when you were late due to some reasons or how well you communicated with other employees in the former company, how much you focused on the work, and so on.

If such is not related to your current application job. How do you deal with conflict? As everyone knows, conflict is a common issue at workplace.

It occurs in every organization now and then. An employee cannot perform his duties well all the time if he is unable to deal with the smallest conflict at work. What about you? Do you have the necessary skills to deal with the most basic conflict at work? Do you avoid it or face it? In this question, you should first state a conflict at your level, choose an example and adopt your skills in resolving such conflict.

Then demonstrate how you do it to the interviewer. Basing on this question the interviewer wants to know how you plan on achieving your goals for the future and what you are going to accomplish. In order to respond to it you could see examples of good responses included: How will you achieve your goals? What negative thing would your last boss say about you? This question is about your weaknesses. In fact, it is a very hard question for a candidate to answer as it is very difficult to be honest with oneself and say out loud about negative comments on himself.

The method here is to approach the weaknesses, or particularly the comments on those weaknesses, in a positive manner. Anyway, I have learn since then the skill to delegate and cooperate with others to complete the job more effectively. Who was your best boss?

Each boss that I worked for taught me a good lesson. What to do from the advice of good ones and what not to do from the challenging ones. From the beginning of my job, a mentor assisted me a lot, and now we still keep in touch. Truly speaking, I have learned something from each boss that I have worked for.

Explain what has disappointed you most about a previous job? Answer tips: Possible answers: Safe areas are few but can include: Not enough of a challenge. You were laid off in a reduction Company did not win a contract, which would have given you more responsibility.

Lack of challenge. How many hours I have to commit. I focused on pay and benefits when I took my job. I would definitely consider this if ever looking for another one. Are you willing to relocate? Relocation is usually inevitable and almost always a condition of employment. This is completely up to you. Be honest, but you should probe the interviewer for more details. Maybe the office location you will be working at is planned to be moved in the next two years and that is the reason for this question.
