BitTorrent Front End Developer interview questions

Got a referral from someone currently working there. Spoke to internal recruiter on the phone - no introductions, or questions about my interest in the company. Just how my JavaScript was. Then sent me a code challenge with insufficient instruction and a request to build something with a deprecated API (head of engineering was out on vacation). I handed in the challenge and was told they would get back to me with an answer, shortly. Never heard from them again.
