Datassential interview questions

Recruiter reached out to me about a job. Hr screen was standard questions about my experience. They asked me to complete an assessment which was to write 2 pages about how I worked on a product team and preferably tell them about an ai project I worked on. I did not spend much time on this as I figured at this point the job wasn’t real. I was ghosted until they reached out to tell me they wanted to interview but wait for approvals. A week later they told me the job was not approved. At this point I think this company was just stealing ideas and fishing for information about how other companies are using ai within other companies.
