Had an initial call with the recruiter and it went well. He then sent me the second stage which was a code challenge and asked me to complete it in 48 hours (he sent me the challenge on Friday at 10am). I worked on it thought out the weekend even though I was very busy. I then sent it back and never heard anything from them, not even a rejection. This is very unprofessional, especially after asking someone to do a code challenge that takes 8 hours +
