References for other interview question articles
- Have you learned something new or interesting lately?
- Make sure you know all the relevant news and blogs. You shoud be reading them regardless, but doing so on a daily basis during your job search is important. Be ready to talk casually and fluently about the latest web trends.
- Why did you get into coding, programming, etc.?
- “Because I can make good $,” “I don’t like to dress up or shave,” and“because I loved the movie Hackers,” are not good enough. Well… a comment about Hackers might fly but make sure you have a real backstory that describes your “Aha!” moment.
- What is your preferred development environment?
- This is your chance to talk shop and demonstrate some industry knowledge. Be prepared to talk about your favorite editor, browser, plug-ins, operating system, and other tools. Freshen up on your lingo.
- What is the coolest thing you ever coded? Do you have any personal projects you are working on?
- These two questions are interchangeable. Any developer worth his weight had to practice somewhere or on something before they landed their first gig. If not, how did you get this interview anyway?! Review your past experiences, and even if they were boring to you, figure out a new frame of reference that demonstrates passion and a zest for learning.
General Website Optimization Questions
- How do you optimize a website’s assets?
- There are a number of answers to this question: File concatenation, file compression, CDN Hosting, offloading assets, re-organizing and refining code, etc. Have a few ready.
- What are three ways to reduce page load time?
- Again there are many answers here: Reduce image sizes, remove unnecessary widgets, HTTP compression, put CSS at the top and script references at the bottom or in external files, reduce lookups, minimize redirects, caching, etc.
- What kind of things must you be wary of when design or developing for multilingual sites?
- Another problem with many solutions: setting the default language, using Unicode encoding, using the ‘lang’, being aware of standard font sizes and text direction, and language word length (may affect layout).
- What is HTML?
- HTML stands for HyperText Markup Language. It is the dominant markup language for creating websites and anything that can be viewed in a web browser. If you want to get some extra bonus points, you can learn the history of HTML and throw in some obscure facts.
- What is the difference between HTML elements and tags?
- HTML elements communicate to the browser how to render text. When surrounded by angular brackets
<>they form HTML tags. For the most part, tags come in pairs and surround text. - What is “Semantic HTML?”
- Semantic HTML is a coding style where the tags embody what the text is meant to convey. In Semantic HTML, tags like
for bold, andfor italic should not be used, reason being they just represent formatting, and provide no indication of meaning or structure. Thesemantically correct thing to do is use. These tags will have the same bold and italic effects, while demonstrating meaning and structure (emphasis in this case). - What does
DOCTYPEmean? - The term
DOCTYPEtells the browser which type of HTML is used on a webpage. In turn, the browsers useDOCTYPEto determine how to render a page. Failing to useDOCTYPEor using a wrongDOCTYPEmay load your page in. See example: - What’s the difference between standards mode and quirks mode?
- Quirks Mode is a default compatibility mode and may be different from browser to browser, which may result to a lack of consistency in appearance from browser to browser.
- What are the limitations when serving XHTML pages?
- Perhaps the biggest issue is the poor browser support XHTML currently enjoys. Internet Explorer and a number of other user agents cannot parse XHTML as XML. Thus, it is not the extensible language it was promised to be. There are many other issues. Take your pick.
- How many HTML tags are should be used for the most simple of web pages?
- 8 total. 4 pairs of tags.
Simplest page ever! Doesn’t get simpler than this.- How do you make comments without text being picked up by the browser?
- Comments are used to explain and clarify code or to prevent code from being recognized by the browser. Comments start with “
*“.
- What is the difference between linking to an image, a website, and an email address?
- To link an image, use
srcin the opening tag. For hyperlinking, the anchor tag,, is used and the link is specified in thehrefattribute. Text to be hyperlinked should be placed between the anchor tags. Little known fact:hrefstands for “hypertext reference.” When linking to an email, thehrefspecification will be“mailto:send@here.com.”See examples below:
parbjotblogspotEmail Me- My hyperlink or image is not displaying correctly, what is wrong with it?
