Show HN: Negotiation roleplays for candidates and for fun (Demo without Login)

Dear Hackers,

for a friend of mine I recently developed a prototype that allows him to let the job candidates for sales positions prove their negotiation skills.

I now turned it into a public demo, to get your feedback.

We have two situations: House Negotiation and Hostage Takers (coming soon).

Have fun and tell me what you think.
