IGG Canada interview questions

I passed HR screening and then received the Art Test. Didn’t pass it, so had no other interview steps. The screening was really nice and informative to me and HR specialist.

They wanted me to do a 30+ hour unpaid art test after signing an NDA. The scope of the test was not clear before I took it on. After completion of the project long art test, they contacted me a day later to say I wasn't 'the right fit.' I asked for feedback on how I can improve for next time an oppertunity came around, and they rudely told me they do not offer feedback because they have too many test taker's to get through. 30 hours of my life wasted without even receiving feedback is appalling.
