Update 3/28/06: Still looking… not for a web designer but a web front-end engineer. Jemery does a good job of describing the distrinction. No doubt about it, this is a hot skill set that is extremely hard to find!
Here’s a tip if you’re considering applying, the first thing I’ll do is go to your portfolio website and do a view source. Save us both time and only apply if your portfolio website W3C validates XHTML and shows proper usage and understanding of CSS. While I’ll eventually look at the work you did for other companies, I generally take it for granted that you did your portfolio site by yourself so it weighs more heavily than anything else! Having a blog is also a good thing, it’ll show me that you have enough enthusiasm for the work you do to take the initiative to write about it!
Of the 40 or so portfolio websites I’ve visited today, only 1 person’s validated and demonstrated proper usage of XHTML and CSS. Please, is the bar really that low? Disprove my pessimism and leave a link to your kick-ass validating XHTML portfolio site (or a friends) as a comment here, even if you’re not looking I’d like to see some better examples than I’ve seen today!
