Stylight Visual Designer interview questions

I got an invite from a recruiter for a short screening interview (15min). After 10 days I received a standard rejection email that I was not shortlisted for any further consideration. I responded immediately asking for more detailed feedback but I got no response. I followed up a couple of days later asking for feedback but again no response. My advice to the company: Instead of responding here on Glassdoor with a standardised response, try to respond to candidates emails instead. You will get less negative reviews from rejected candidates.
