Curriculum Associates Professional Development interview questions

I applied and received an email within only a few hours to set up an initial phone screen. I had a great conversation with the hiring manager, who sounded positive and gave me the name of two people, and said I would be hearing from one of them to set up the next interview. She even gave me her personal cell phone, should I have any questions. After a week, I followed up and asked if she needed anything from me. She did not respond to email or text. A few days later, I emailed the HR person who initially reached out to me. We emailed back and forth for 3-4 weeks: I would follow up, she'd get back to me after 2-3 days and say she would have an update for me within a certain amount of time (a week or so). I'd wait until after that time frame, email again, and the process would start over. Eventually she told me they had hired someone else.

I made it to the third round of interviews for the position I applied for. I had an initial phone interview with the talent team, an second phone interview with regional managers, and a third in person interview at the office in Billerica
