<p><a href="http://www.abovethelaw.com%5B/url%5D">www.abovethelaw.com</a> did an article on this awhile back where they talked to numerous recruiters and headhunters who said they target 2-4 yr associates for in-house positions and that after 4 years their marketability decreases because they are older and more engrained in the biglaw way of law. abovethelaw is run by David Lat, harvard ug, yale ls, wachtell associate (#1 firm in world).....if he decides to write it and cite numerous headhunters I'll take his word for it.</p>
