Cengage Editor interview questions

I've interviewed for them twice. The first time I didn't get a job offer but didn't receive any response from them for months, until I finally got a form email telling me that I didn't get the job. A few months later they contacted me again to interview for a similar position. Still not sure how that went. My interview as about two months ago and haven't heard anything back from them. The hiring manager hasn't replied to my emails, so I'm just assuming that they ghosted me again. Six separate interviews and they ghosted me twice.
