Apps10X interview questions

Applied for the position through linkedin and they reverted asking for few basic details like total experience, salary expectations etc. Then a task was shared to build a simple application within 2 days . The task had some basic expectations and some nice to haves. Submitted the task on time with both the expectations and nice to have implemented. Then they ghosted me. Sent multiple follow up mails and messages on linkedin but didn't hear back . I asked for a feedback on the task submitted. Since I have spent time on that ,the least decency they could have is to share some feedback.
