It's a great question and I ask that question all the time. However, unlike the blog writer, I am looking to weed out those that are looking to become managers soon. If you are looking to get a development job as a stepping stone to a management position in 3 years, then you're probably not a software engineer I am looking for. (One of many factors, of course...)
This is what I fear. I fear that some hiring manager is going to make a career choice for me. I chose to interview with his company for a specific position, my choice of career path.
