Web 2.0 is a trend in the use of World Wide Web technology and web design that aims to facilitate creativity, information sharing, and, most notably, collaboration among users. These concepts have led to the development and evolution of web-based communities and hosted services, such as social-networking sites, wikis, blogs, and folksonomies (the practice of catgorising content through tags). Although the term suggests a new version of the World Wide Web, it does not refer to an update to any technical specifications, but to changes in the ways software developers and end-users use the internet.

A database index is a data structure that improves the speed of operations in a table. Indices can be created using one or more columns, providing the basis for both rapid random lookups and efficient ordering of access to records. The disk space required to store the index is typically less than the storage of the table (since indices usually contain only the key-fields according to which the table is to be arranged, and excludes all the other details in the table), yielding the possibility to store indices into memory from tables that would not fit into it. In a relational databasean index is a copy of part of a table. Some databases extend the power of indexing by allowing indices to be created on functions or expressions. For example, an index could be created on upper(last_name), which would only store the uppercase versions of the last_name field in the index. Another option sometimes supported is the use of "filtered" indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.

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.
