> They presented three design challenge options to pick from, with a weeks notice and advised that we should spend no more that 3–5 hours on the task (wink, wink)
I know this self-selects for people willing to do extra work for no extra compensation.
However, let me play devil's advocate for a minute as a thought experiment. I would actually worry that this issue is also a self fulfilling prophesy. If I'm told to do X in Y hours, but it takes me 10 x Y hours perhaps the employer really does expect it to take only Y hours. Maybe the typical workload at that employer is for someone who really can do X in Y. As long as that is properly compensated, I see no problem with that. If the employer is asking for an extremely high caliber developer, and will also compensate as such then it's no issue. However, an average developer applies and thus has to lie about what they can achieve in that time-frame. Let's say they get the job and then when the workload is dumped on them it obviously takes longer than the 40 hour work week and they cry about "self selecting for people willing to work extra for no compensation." When in actuality, the employer expected, based on a false presentation, that it was within the average developer's abilities.
Of course, I'm being somewhat satirical and without knowing the exact position and compensation being offered (as compared to average) no one can say if this is the case.
