C2 Research interview questions

I was greeted very warmly and felt very comfortable during entire interview. The interviewer asked questions about me and what my career goals were and seemed very interested in the job being a good fit for me as well as for them. She then very clearly explained the job expectations and wanted to know my experience with Excel, Salesforce and Google Drive. She answered all questions I had at the end and gave me a timeline of when I should expect to hear back about a job offer.

I'm emailed my resume after seeing their job posting on Craigslist. I was skeptical as to if they were a legitimate company. I was contacted through email to set up an interview a week later. After I answered their first question, they immediately offered to interview me for an internship instead. I got the feeling they didn't want me for the position right of the bat, so they made me feel as if I didn't have any sort of research experience. I currently had a job in research prior to the interview, and was not about to take an underpaid part time internship. The interview was quite unwelcoming.
