Dunn Solutions Frontend Web Developer interview questions

Contacted to set up a virtual interview. Completed the virtual interview with someone else in the company and was blindsided by technical questions as this was not indicated would be the topic of the interview in the initial contact I had with the person who originally scheduled the interview. I asked at the end of the interview what next steps would be and was told "I don't know" and to ask the person who originally scheduled the interview. Reached out to this person asking for next steps and never received a response.
