International Business Promotion interview questions

Received a call out of nowhere, no previous prep time to review for an interview, no introduction from the speaker, no introduction about the company. Launched straight into questions as to why I was applying for that position, but again they did not identify which position I had applied for or confirmed anything besides my last name. The person was very rude and impatient as I tried to figure out which company they worked for in order to pull up the information of my application and the job description. The lady attempted to cut me off from trying to pull up the job information, and told me to call back later when I "was more prepared." It was a baffling experience, and I would never recommend interviewing or working for this company based on how they ran this procedure.
