Explain the first 10 lines of Twitter's source code to me
I&#x27;m sorry but if a place I was interviewing for asked me this I&#x27;d end the interview and move on. This is about as useful as knowing how to write C boilerplate on paper from memory (something a college professor had us do for an exam), which is to say it&#x27;s completely useless.<p>&gt; The first line of every document’s source code is perfect for this interview because how much a candidate knows about the DOCTYPE declaration closely resembles how many years of experience they have.<p>This just screams &quot;I have some esoteric knowledge and I&#x27;m going to lord it over you&quot;, sure I remember vaguely when the html doctype first came out but knowing what that does doesn&#x27;t make me a better programmer. I write that line 1 time max in a project and then never think about it again. Why would you ever harp on that? Especially when most frameworks your are going to be using handle that all for you or it&#x27;s in the default header block&#x2F;index.html?<p>Talk to me about how I&#x27;d solve a problem or how I&#x27;d architect something but don&#x27;t quiz me stuff I rarely need to know. Even PHP argument order (a near-useless skill) is more useful than this list. Give me 5 minutes on google and I&#x27;ll tell you what every single one of the tags mean&#x2F;do (the ones I might not know off the top of my head), that&#x27;s a way more important skill then being able to spout off what they are from memory.
