I was left standing outside for a good few minutes before they answered the doorbell. One of the interviewers began the interview by stating to the other interviewer "I told you so" about me. I'm unsure what that meant, but it seemed to be an insult. The interview consisted of a review of my resume, standard interview questions, and a quite a few hypothetical scenarios. After the interview was over, their behavior was very strange. They were silent the rest of the time as they were guiding me back to the entrance of the building and didn't even say goodbye to me or anything when I left. They never got back to me and never updated me if I was selected or not, I only found out that they didn't choose me once the job posting closed. Overall, the process was pretty unprofessional and strange.
