MDI (Multiple Document Interface) is a Microsoft Windows programming interface for creating an application that enables users to work with multiple documents at the same time. Each document is in a separate space with its own controls for scrolling. The user can see and work with different documents such as a spreadsheet, a text document, or a drawing space by simply moving the cursor from one space to another.

An MDI application is something like the Windows desktop interface since both include multiple viewing spaces. However, the MDI viewing spaces are confined to the application's window or client area . Within the client area, each document is displayed within a separate child window . MDI applications can be used for a variety of purposes - for example, working on one document while referring to another document, viewing different presentations of the same information, viewing multiple Web sites at the same time, and any task that requires multiple reference points and work areas at the same time

Your answer should be relevant to the job for which you are being interviews. Do not start going into your personal life. Keep your self-introduction PROFESSIONAL.

A person is defined in three ways: (1) who he is right now, (2) what he has done in the past, and (3) what he will become in the future.

So, here is how you answer: (1) I am a [the job title for which you are applying or something very close.] (2) I have [how many years of experience] in [what field, what subject]. (3) I want to be [a job title that is a couple or a few levels above the current position for which you are applying in 5 to 10 years.]

Close your answer with an affirmative question: "Is there anything else you want to know?"

Here are more suggestions for answering this very common interview question.

• You should be very straight forward and honest in replying to this question. The interviewer wants to check if what you have mentioned in your resume is correct or not.

• I would answer the question based on who is interviewing me? If it's a sales manager/Technical Manager/Human resources manager? Depending on the person's field I'll have to mend the answer to please him...I feel that everyone's goals are different...so anlayse that and then answer.

• Answer this question with your 30 second "elevator speach" about yourself. The standard format for this speech is... "I am a (BLANK), who does (WHAT)." In my case... I am a PROJECT MANAGER, who PROVIDES QUALITY MANAGEMENT SOLUTIONS, Blah, Blah, Blah. (you get the idea).

• The Answer can Start like this: "I have 10 years' sales rep experience, working in a variety of industries, from retail to advertising. For the past two years I have been working in the food industry. In addition to my successful sales techniques, I have a great record for forming long-standing relationships with customers. I'm a team player who thrives on challenge."

• Let me share what my recruiting office tells its candidates as they head out for that crucial face-to-face interview. When asked to "tell me about yourself," say, "I will gladly answer that question, but may I first ask you a question? (They ALWAYS say yes) So that I may better focus my answer, what are the issues you want me to address should you hire me? Once they share with you what they need to have you do, then proceed to address how your training, education, skills, and experience can best resolve these issues. By answering in this fashion, you have proven that you know how to focus ... and that you have what's needed to fix the issues they need to have fixed. It's always a winner ... and beats the heck out of, "Well, let's see, I was born on a small farm in Idaho ..."

• I am a self-starter dedicated, hard-working person who works well with other, punctual, detail oriented a team player, great organizational and interpersonal skills.

TRAPS:  Give a perfect "10," and you'll seem too easy to please.  Give anything less than a perfect 10, and he could press you as to where you're being critical, and that road leads downhill for you.

BEST ANSWER:  Once again, never be negative.  The interviewer will only resent criticism coming from you.  This is the time to show your positivism.

However, don't give a numerical rating. Simply praise whatever interview style he's been using.

If he's been tough, say "You have been thorough and tough-minded, the very qualities needed to conduct a good interview."

If he's been methodical, say, "You have been very methodical and analytical, and I'm sure that approach results in excellent hires for your firm."

In other words, pay him a sincere compliment that he can believe because it's anchored in the behavior you've just seen.
