A fair chat with HR and hiring manager for the first two rounds. Then took me to wait for two weeks to present the task which instructs to make it not technical but presentable to client marketing team. End up the hiring manager only focused on the technical side and expected to pairing two unrelated metrics for their desired visualization. Also not quite attentive to my presentation, asking questions that already mentioned. They didnt understand the model and logic behind and just say there's error. Apparently it's not. They don't have enough business sense and kind of changing the gate holder. If you aren't intended to do this hiring, can say it upfront rather than playing games.
