Two hours of messing about on Instagram trying to get an authentication token for their API I eventually figured it out, only to realize I was authenticated in some sand boxed mode, so only meta-data was being returned. I needed to have the acccount approved before I could use it properly.
That was a waste of two hours of my life.
If you told me to do this take home assignment I would've politely smiled and said 'sure let me do it right away'. Then I go home, research more about your product and the market, try out your demo product, figure out how things work and release an open source version and make it free. Surely, that is a much better indicator than 'Build a CRUD using Yii'.
A few years ago, I did this to one company I interviewed at who were super arrogant and condescending. I just checked their website and it returns 404. Looks like people prefered my free open source version instead of paying them for it.
Don't fuck with me.
