Xindong Network interview questions

The process leading up to the interview was fairly smooth. However, during the interview it became apparent that the hiring manager did not prepare for it by reviewing my portfolio. I had to resort by showing whatever I had on my old smartphone. The interviewer mainly focused on my early career and did not ask a single question about my biggest project. They also continued by asking some shady questions regarding my previous companies resources. Which certainly left me with a bad first impression. The reply about the interview came late and with an emoji (how professional) after I had to chase them up on it, and did not provide the feedback that was specifically mentioned before.
