Media Graph interview questions

I received randomly call and asking about details, told me that they will send a test which is atleast 4-5 hours work. I complete test before deadline and their is no any answer regarding my test feedback or job position. I feel that was wasting of time.I complete test after complete my working job hours and I don't even deserve one followup email. Horrible experience

There was a phone interview, after which there was a one one one interview followed by actual solidworks design test in which I was given an electrical component to 3D model and create 2D drawings for it.
