Eagle Eye Networks Software Engineer - Java Developer interview questions

I applied through LinkedIn EasyApply and I was invited for a first interview. It was a disappointing experience as the interviewer was unaware and confused on how to proceed with the interview at first. The interviewer did not have questions prepared to ask me. Interestingly, it was expected of me to have a sound knowledge of the company at the interview. This is not surprising as an HR intern was sent to interview for this position. However, it is disrespectful of the candidate's time and effort. I hope this does not happen again with someone else.
