Observe.AI Software Development Engineer SDE 3 interview questions

I was contacted by a HR in January and then ghosted after providing availability. I was reconnected with the same HR after 2 months who now scheduled the initial discussion with the Director. The Director seemed absolutely disinterested in the conversation as throughout the interview he was yawning, leaning and showing all signs of disinterest. not a single project was dived deep into , not a single point did he note down, Infact at one point he simply asked about something which I had already explained . This was the most infuriating discussion in my entire life.
