job-talent-us.firstwork.com

How do I know if a link is a scam? My GF has been applying for jobs online. Earlier today she received a text to a supposed job application with a url shortener link, but the fact that they used a url shortener immediately made her suspicious of a potential scam. The url shortener led to "job-talent-us.firstwork.com." I first googled 'firstwork.com scam?' and results said it was legit. But then I googled 'job-talent-us.firstwork.com scam' and the AI results said it was a likely scam. However, the sources cited by the AI were only reddit comments that didn't really conclusively support the claim that the link was definitely a scam, and other non-ai search results weren't very helpful one way or another. In general, I think I've gleaned that a common scam targeting job seekers involves fake websites impersonating the otherwise-legit 'firstwork.com' and 'jobandtalent.com' websites. But I haven't been able to determine whether the particular link my GF was texted, to 'job-talent-us.firstwork.com' , is legit or not. I don't really know how urls work - is the fact that the domain ultimately ends with 'firstwork.com' enough to trust that it's just part of the legit firstwork.con website, even though it's preceded by that other stuff ('job-talent-us.')? If anyone knows about any part of this, please share your insight.
