I answered a few online questions and then was invited to give a presentation and formal interview. The questions were standard and fine. I was sent some scenarios to respond to that I had to hand in by 5 the next day. I then heard absolutely nothing. I sent a follow up email and got no reply. I then heard back randomly, via email about 5 weeks later informing me that I was unsuccessful with 0 feedback. Unprofessional, disorganized and disrespectful. It's common courtesy to reply back to an email, let alone not replying at all.
