[Edit: corrected typo]
For example I had one interview where I struggled to complete a WPF test project simply because it was coded in a way i've never done before using controls I've never used and the test was estimated to take 10 min. Meanwhile in my bag on my laptop I had a complex WPF solution i've been working on in my free time for months as a possible product to market and sell which more than showed my competence in the platform. People in my interview didn't even want to see it on pretext that they have no way of knowing it's my code.
Waste of time also, especially if you factor in a 2 hour commute each way.
It's generally inappropriate for someone to ask you to do more than a day of work for a take-home hiring exercise.
They might have a different point of view as to the quality of your work. Or they may have taken other factors in consideration (your portfolio, communication style, etc).
But not contacting you with any kind of a status afterward is definitely shabby, on their part.
And asking you to do a second assignment without taking a moment to evaluate your first (and apparently without bothering to tell you in advance that not one, but two or more "quick" assignments would need to be done), all the more so.
