Made it to the end of the interview. Was told I got the job, but had not received the official offer yet. They ghosted me for a week and hired my coworker without any communication.

Interview process was a total of about 2-3 months. Initial call was beginning of October. Following week, had a phone interview. A week or two later, had a panel interview at the corporate office with 3 different people (about 30 minutes each). The next day, had a Zoom interview with another person. This was mid November. I never heard back from the anyone. I followed up sometime mid December. They didn’t respond until January saying the position went to someone else.
