Thoughtfish interview questions

They send a timed 4 hour test and you need to submit it within the deadline. The test is scheduled as per candidate's availability and the email arrives on time. I attempted the test as much as I can in 4 hours and submitted it. It was more of a speed programming contest. There were 2 mini demos (2 questions) that needed to be implemented as unity projects and delivered back. I have 5+ years of unity experience and the amount of work needed to be done was around 8 hours. I attempted 1 task out of the 2 and believed it's not the completeness but the quality of done code that matters I have given several interviews in these days and every game studio provides approx. 3 days test and this was the first time 4 hour timed test was given which for me couldn't be completed in 4 hours. It was challenging and you need to write clean, modular code as this will be judged After the test was submitted I never heard back for 8-10 days, upon multiple emails for the feedback I got a 1 liner email that they won't be pursuing with me - which is totally fine but atleast provide the detailed overview for candidate so that he/she can improve him/herself and know where they fell short Upon multiple emails there wasn't any response and I was completely ghosted. I don't know it they expected the code to be completed, or it's the code quality or they have already hired someone else and my submission was completely fine I don't know. I deserve a feedback and every company do provides it, it only take a few lines
