Completed recruiter screen, and scheduled for a 45 minute technical. I asked and was specifically told there would be no white boarding, that it would just be a conversation to learn more about my technical background. The interview was just tech-trivia, no questions about my actual work experience. After 30 minutes I was asked to open a google doc, share screen, and complete an algo that was pasted into the call chat. After I completed a solution, I was asked to optimize it. At this point I addressed that we were at 45 minute call length. The interviewer told me that the interview should have been scheduled as 1 hour, and 45 minutes was incorrect. He then asked if I had somewhere to be, I did not and completed the algo as asked.
