If you are asked to list your negative qualities - no need to proudly claim if you do not, or flirtatiously claim that you are hardworking and terribly unbearable professional. It is unlikely that specialist personnel appreciate the joke, which has already become commonplace. Better call your 2-3 negative traits that will not interfere with work. For example, if you'll be working with papers, not with people, you can afford to be grouchy, withdrawn, boring or shy.
Talking about the experience, give specific figures, talk about success, about the benefits that you have brought the organization. Do not need to say that you, for example, organized a successful advertising campaign. Tell me what your advertising campaign to increase revenues by 15% the organization and attracted 5,000 new customers and 5 partner companies.
Surely you are asked why you left the former place of work and if you like it. This is a very dangerous question and answer to be cautious. Do not allow yourself to criticize the management and staff - you deem ungrateful, unable to find a common language with other people. Say that you have worked in a remarkable organization with an excellent team, gain valuable experience, but eventually realized that you have no prospects of development. You want to develop as a professional, and decided to change jobs.
And finally, the most tricky question: "Why do you want to work from us?" To answer this question, before the interview, carefully review the history of the company. Locate the main advantages of the organization where you want to work. For example, you can say that you want to work in a young, growing company, as can thus improve their skills and gradually climb the career ladder. Or, on the contrary, the company is right for you, as there are for many years, its reputation is impeccable, and the work of such an organization - it is an honor for any professional.
