Gradiant interview questions

After extensive back-and-forth over chat I was able to schedule a call, mostly thanks to a friend already working for Gradiant who'd recommended me. The call was extremely casual and the interview focused primarily on restating what I'd already listed in my resume and confirming that I was interested in a temporary position covering another associate's leave period. Following that call I was never contacted or responded to again via any channel. I found out later that the individual who'd interviewed me was no longer with the company. Clearly there were other issues behind the scenes that impacted my experience, but it's still very difficult to recommend based on what I saw.

The interview went very smoothly. I got positive feedback. However, they asked me to wait so they could interview other candidates, as per their process. They kept me waiting for three months and never got back. I understand if a candidate is not a good fit, as I have been on the hiring end of the table. But keeping them waiting without proper communication is a bit arrogant. HRs should understand that it's only a two-way street, both the employee and the employer benefit.
