Aren’t XML, SGML, and HTML all the same thing
Not quite; SGML is the mother tongue, and has been used for describing
thousands of different document types in many fields of human activity,
from transcriptions of ancient Irish manuscripts to the technical
documentation for stealth bombers, and from patients’ clinical records
to musical notation. SGML is very large and complex, however, and
probably overkill for most common office desktop applications.
XML is an abbreviated version of SGML, to make it easier to use
over the Web, easier for you to define your own document types,
and easier for programmers to write programs to handle them. It
omits all the complex and less-used options of SGML in return for
the benefits of being easier to write applications for, easier to
understand, and more suited to delivery and interoperability over
the Web. But it is still SGML, and XML files may still be processed
in the same way as any other SGML file (see the question on XML
software).
HTML is just one of many SGML or XML applicationsâ€â€the one
most frequently used on the Web.
Technical readers may find it more useful to think of XML as being
SGML– rather than HTML++.
5 Questions to Dazzle Would-Be Employers
To make sure your next interview is as smooth as your freshly pressed suit, try these 5 questions on for size: 
1. "How do you see me benefiting the company?"
Finding out why you were selected out of possibly hundreds of other candidates gives you a chance to expand on the qualities that caught their eye, further making the case for your hire.
2. "What would my first project be if I'm hired?"
This will give you a specific idea of what you can expect when you walk into the office that first day after being hired. It also can give you a heads up as to what will be expected of you, allowing you to build on those attributes during the interview.
3. "What is the company's culture?"
This will reveal those "intangibles" of a company that have nothing to do with professional experience or required education. If you need a traditional, office/cube environment to stay focused and get the job done, a more creativity-driven workplace which allows music streaming from computers, nerf hoop tournaments and ultraflexible schedules may not be conducive to your productivity.
4. "Who will evaluate me if I'm hired?"
Ask this question, and you'll discern the company and departmental structure under which you will be working. For instance, will you report directly to the vice president or will there be a succession of middle managers between you?
5. "When will a decision be made on the successful candidate?"
Knowing this helps you determine the timing of your interview follow-up activities.
