Stack Builders Software Developer interview questions

I had an interview with HR and asked for a salary that aligns with the average for this role in my country. They mentioned it was too high, but we agreed to proceed. They then sent me a technical assessment, which took several hours to complete. A week after submitting it, I received a generic rejection email with no feedback. It is quite frustrating to spend your free time working on a tech assessment and not getting any feedback at all, I don't mind getting rejected but at least let me know what I can improve in.

Lame, i passed all the tests on the on the coding Challenge and still didn't pass answered all the questions maybe i missed one or two. Still didn't get a call back.
