Then, they canceled one round just 5 minutes before it was supposed to begin.

Another round was rescheduled with a different interviewer. Some of the questions were about backend technologies, giving the impression that either the person didn't know it was a Frontend interview or wanted to show that I lacked knowledge. Also, they presented an algorithm problem for which there were only 5 minutes left. I barely had time to think.

The third round went smoothly and on time, with the interviewer being friendly and welcoming, and all questions were on topic.

Another thing I didn't like was that none of the interviewers turned on their cameras. It was very uncomfortable.

What is the flow of Redux?
