Ruckus Marketing interview questions

I had an initial call with the CTO, then a week later a more technical interview with the CTO and another dev. They asked me basic React/JS/Web Dev questions. I believe I answered ok, because they moved me to the takehome. The take home was using the zomato api and building a simple React application with it. I was disappointed because they ghosted me with 0 feedback after I invested hours into them. Very unprofessional.

They called and asked me to write an article for them and I did they said they will call back but did not they didn't even have the basic manners to send an email regarding the same totally unprofessional behaviour
