Mirriad Software Developer Interview Role interview questions

I applied online. I interviewed at Mirriad screen call with HR technical interview with one of the team member. People in the company is friendly, so don't get me wrong. However, I would like to provide some suggestions. I think the company did not know what person they are looking for. When I advance to the 2nd stage, I felt shocked as the skillset I have did not match their requirements. So why did I go there and spend my time? hope the company can improve internal communication or be more careful.
