I don't know how hard it will be to land a tech job in general, but for any individuals I know it will be more difficult. It gets much harder in your thirties, and a damn near impossible to get a development job by the time you are fifty. You had better have made you millions and retired by then. I recently landed a job at a startup and couldn't be happier, but it was a helluva struggle to overcome pervasive cultural biases that favor less experienced coders right out of college.
