I applied through an employee referral, who thought I might be a fit for the role and suggested I apply. I went for it (no harm) and had a great time speaking with the hiring manager as well as the MD about the industry and the things we do, as well as sharing ideas for the industry. However, they went silent and there were completely no updates from the HR person who arranged for the interviews (and pretty last minute, and she was rushing me at night to come back with suitable time and dates for the next day). I only heard from the friend that someone else had gotten the job (they sent out new employees notifications) but completely zero updates from the HR or hiring manager. That was a bit unprofessional.
