Corcus interview questions

I applied online. I received a response from Corcus a few days after I applied requesting for a phone screen. During the phone screen, we discussed about my background and more about the role. At the end, I was informed by the hiring manager that Corcus would send me information about follow-up steps. I waited approximately 2-3 weeks for Corcus to get back to me, but did not receive any email or message. I emailed them 3 weeks after my phone screen and Corcus responded that they already filled the position.
