Zorvyn hiring scam or legit? (INR 18 LPA Associate role)

I just received an offer letter from Zorvyn for an Associate Software Engineer position with a CTC of 18 LPA. The weirdest part is that I only gave an Online Assessment (OA) test—there was absolutely no interview and no discussion with an HR representative before this offer landed in my inbox.

I’ve seen several warnings on Reddit and YouTube claiming this company is a scam, and the lack of a proper hiring process is a massive red flag.

I have few questions... Does anyone actually know about this company or have a real experience with them?

Why are they doing this?

What is the point of putting in the time and effort to create assessments and offer letters if it's all fake? It seems like a useless waste of their own time too.
