"What did you like/dislike about your last job?"
The interviewer is looking for incompatibilities. If a trial lawyer says he or she dislikes arguing a point with colleagues, such a statement will only weaken - if not immediately - destroy his or her candidacy. Most interviews start with a preamble by the interviewer about the company. Pay attention: That information will help you answer the question. In fact, any statement the interviewer makes about the job or corporation can be used to your advantage.
So, in answer, you liked everything about your last job. You might even say your company taught you the importance of certain attributes from the business, achievement, or professional profile. Criticising a prior employer is a warning flag that you could be a problem employee. No one intentionally hires trouble, and that's what's behind the question.
Keep your answer short and positive. You are allowed only one negative about past employers, and only then if your interviewer has a "hot button" about his or her department or company; if so, you will have written it down on your notepad. For example, the only thing your past employer could not offer might be something like "the ability to contribute more in different areas in the smaller environment you have here." You might continue with, "I really liked everything about the job. The reason I want to leave is to find a position where I can make a greater contribution. You see, I work for a large company that encourages specialisation of skills. The smaller environment you have here will, as I said, allows me to contribute far more in different areas."
Tell them what they want to hear - replay the hot button. Of course, if you interview with a large company, turn it around. "I work for a small company and don't get the time to specialise in one or two major areas."
