First round telephone round where hr asked about me and confirm the time and date for interview and then interview basis on the assignment given and it continued for 1.5 hours it was completely based on assignment Provide no DSA pr fundamentals

They gave us assignments in which we had to make two applications, The first was: Rule Engine with AST, and the other was: Real-Time Data Processing System for Weather Monitoring with Rollups and Aggregates. I also submitted this assignment by giving nearly 30 hrs of my week and after submitting it, they told me they were evaluating the assignment and will respond in a week , but they have not responded after submitting the application and giving so much time.
