Applied at Crossing Hurdles for Unknown

I received an email today from a company called Crossing Hurdles, and I’m trying to figure out if it’s legitimate or a scam. They mentioned they were contracted by another company, Terac, to find people for a survey. I’ve seen some comments suggesting that Crossing Hurdles is a third-party staffing company and that this might not actually lead to a real job opportunity. Some people mentioned that the language in their application process, like using the word 'kindly', is often a red flag for scams or ghost jobs. I’m feeling uncertain about whether to pursue this or not.
