Rendered.ai interview questions

I was given a take-home assignment where I reskinned a model in blender and then placed a sun object and rendered the model. I did this and submitted my working assignment a day before it was due. I waited over a week for a response. This response was my recruiter texting me at 3am telling me I didn't get the job a week later. The people at Rendered.ai gave me zero feedback on my submission and effectively wasted half of my week. This is super disrespectful of candidate time and shows this company doesn't care about wasting people's time and then ghosting them.
