Contacted by internal recruiter, short conversation about my background, then was sent a take home test and given three days to complete it. Done it in time, included many test cases and a lot of detail. Recruiter acknowledged receipt of my test, told me to wait theee days. Didn't hear back, on the fifth day contacted the recruiter, got no response. Another person wrote here that they had a similar experience. I guess this is just how they roll. Very unprofessional, especially given that we take our time to do these tests. Not interested in them anymore.
