Sky-Rider Equipment Design Engineer interview questions

The first interview was pretty standard, asked me a couple of questions, clarified the job and its roles showed me around the place, and got to meet the staff and HR manager. This is not why I'm leaving a negative review. After the interview, the company asked me to take a 2.5 hour "test", which would be used to help place me in the company. The test I was told would consist of AutoCad, Autodesk Inventor, and a "math portion", all of which they told me shouldn't be difficult. The test ended up taking 4 hours, with just the CAD portion taking up 2 of those friggin hours since they asked me to do an entire CAD assembly AND Autocad drawing package, and they didn't even give me the math portion of the test until 2 hours into my test (which by there standards would only leave me 30 minutes to complete it). The math portion was a slap in the face since it was basically 5 school problems, all of which you'd never complete in the time limit of 30 minutes WITH NO FORMULAS GIVEN. As a result I wasn't out of there till I was 4 hours in, and left frustrated after the whole process. A lot of my friends said they would've just left after being given a test like this but I wanted to give the company a shot since they seemed like really nice people and the work environment was "like family". But up to a month after, even after I told them I had a competing job offer I didn't receive a single call back. The company wasted 4 hours of my life on this stupid test and didn't even bother to have the decency to at least follow-up. Don't apply to this company, don't take the test they request you to do, and avoid it at all cost. They're basically doing this to get free labor out of you by forcing you to try and do training early for free. I wish I knew how bad this was gonna be when I applied and accepted doing the test, but now I've finally learned to avoid companies that do this.
