The application itself was pretty easy. The interview is where it felt unprofessional.
I applied for the job and got a reply via email asking me to come in for an interview. When I went in for the interview, they had no idea that an interview was happening today. They called for someone to interview me and she looked unhappy to be using her time with the interview.
Turns out they already hired someone for the job. Overall, an extremely unprofessional experience. Don't waste your time.
