Everything seemed legit from internal recruiter contact details and procedure: I've got a lot of reading material from them, set online meetings, etc...
I did the first coding interview and the interviewer has been overly positive throughout the 40 minutes we talked. One day later the former recruiter told me I didn't pass and now he's refusing to give me a more detailed feedback claiming that "due to compliance policy we are not able to provide you with the detailed feedback on your interview"
So...it's this for real or this is some sort of very refined scam (no idea what may be the end goal tho)?
