It's not clear that Ramp is actually hiring for this role; the listing itself may be fake. Submitting even an initial application required completing a technical screening. The screening is not incredibly difficult, but it is time-consuming.

As others on Glassdoor have mentioned, after a correct submission, your application will just be denied anyway, before even talking to a human. Some companies post fake job listings as a way to alleviate employee workload concerns and to falsely signal company growth. I have no way of knowing if that's the case here, but from other Glassdoor posters, that seems likely.
