PTC interview questions

I interviewed for the Vuforia team in Israel. Received a call from HR, scheduled a phone interview with the team lead he asked some basic Node.js questions. After the phone interview recived an Home assignment to build an application in any Frontend framework with a Node.js backend (1 week time). After finising the assignment i've sent it over to the team lead, didnt get any feedback, two weeks later recived a generic rejection email with the HR thanking me for meeting at the office (I've never been at the office). I've expected to recive at least a feedback about the home assignment that i've spent a week working on, and to recive a less generic rejection email. its evident the company does not care for its candidates.
