Smarking Data Engineer interview questions

I had a video call on Zoom. It was scheduled for 45 minutes but it lasted for only 20 minutes. I was asked about four questions, and was told to answer them all together. It would have been better if I was asked one question at a time instead. It was unreasonable to expect me to remember an unknown number of questions. At the end of the call, I was told to that I would be moved to the next round in the interview. Two days later, however, I received a rejection email.
