Classic interview with single interviewer bouncing between talking about the business and asking about my credentials. The interviewer liked me and said they wanted me to come back next week for a secondary interview and they would call me soon to schedule it. After complete silence and them not responding to any of my recruiters messages, they get back to her 3 weeks later saying they already gave the job to somebody else. Because they took so long, they cost me a few potential job opportunities when I'm already struggling to find a full-time position. Overall, very unprofessional
