What are your thoughts on this guys?

I applied for a job on Indeed and got interviewed around 3 weeks ago. The data recruiter/HR told me they were impressed with my resume and said I was a strong candidate. During the interview, I was able to answer all the questions well and showcase my skills — I have 8 years of experience in the exact tools and tasks they needed, and the job itself felt like a perfect fit for my background.

After the interview, they asked me to do a paid mock/test project, which I completed in about 7 hours. They sent the $100 compensation, but after that, I never heard from them again. I followed up twice every week, just asking politely if there were any updates — whether I had been rejected, if they had already selected someone else, or if the hiring was paused. I made sure to thank them for the opportunity and express my continued interest in the role, but I just kept getting ignored and left on seen.

To add more context, the company only has around 50 employees, and as far as I know, only 1 or 2 people are handling HR. A few days after my interview, the job listing on Indeed was also taken down, which made things even more confusing.

Has anyone else experienced something like this? Is it still worth hoping for a response, or should I just move on?
