Hornblower Group interview questions

First step was an in person interview with hiring manager. It went well and was invited back the next day to meet with her soon-to-be replacement. That interview (#2) went even better and was invited back for a 3rd interview the next day. The final interview also went well. 3 interviews in 3 days and never heard a word from any of them after that. I sent several emails to all 3, none of which earned a response. After THREE MONTHS, I finally got an answer saying they put expanding on hold. Incredibly unprofessional on every level.
