Rappi Senior Android Developer interview questions

I applied through LinkedIn jobs and got contacted shortly afterward. The first interview was an HR interview, the interviewer were friendly, he talked for awhile about the company and the process and then asked casual questions. After that interview they sent me a task which i spent about 4 days to craft it and after delivering it. I didn't hear anything from them again even though I sent multiple reminders. It was totally bad experience and I've regretted the time that I spent on that task ! Please respect the candidates and value their time!
