Can I trust this data annotation company?

I applied for a data annotation position on LinkedIn at T-Maxx International. I received an email for an evaluation, completed it, and sent it back. However, it has been a week and I haven’t heard anything.

I recently checked LinkedIn again and saw that they are still hiring for the same position.

Does that mean I failed the evaluation, or could T-Maxx be a scam?

I’m really eager to find a remote job. Can anyone recommend companies that are actually hiring for data annotation roles?
