Crossover for Work Technical Program Manager interview questions

I submitted my application, received an email to confirm my email address and was asked to take an 8 - 10 hour "test". I was able to take the test in increments etc. meaning I could spend 8-10 1-hour blocks instead of completing it 8-10 hours consecutively. At first, I thought this was great! I know my stuff and have no problem proving it but then I studied each "assignment" and pretty much felt like it was a way to get free work and ideas from candidates. To complete those assignments would require time to create visuals or source some from the web, research and lots of analytical thinking. Then, find a way to summarize into 2 slides. I understand that they are trying to weed out qualified candidates, but its best to ask for examples of work completed, not for ideas about new features for their WorkSmart product, processes etc. Kinda sucks...because the company seems decent, but my time is precious and I don't give away free ideas. Hire me and then you get my brain. As far as the proposed salary - it's about 30k below what I would earn as a Senior PM, however working remotely is a nice perk so didn't mind the lower salary.
