Intelligent Automation interview questions

Composed of 3 interviews of increasing duration and technical difficulty. No actual live programming, but they will drill you on everything you put on your resume. They seem to be looking for people with diverse backgrounds for this role (physics, mathematics,...)

Worst experience ever. I have completed all the interview process (1) screening, 2) speaking with the hiring manager, 3) finally onsite with close to 10 people in a single session asking questions about 'their expertise' , without a single person having his/her camera on, 4) reaching out to references). And then? Nothing! They never contacted me again, neither did I. It is so disrespectful and unprofessional to at least let the candidate (you spent hours with) know about your decision. You may choose to move on with another candidate or even may not want to make an offer to any candidate, and this is totally understandable. However, you have to respect any candidate and appreciate their time (and even your time). Given that and after seeing they publish the same job posts again and again, I am not even sure that they want to hire anyone. It feels like they just want to be seen they are a big company and hiring a lot of people or they are looking for someone with the experience of a hands-on professor who is willing to work for less than 90K in DC area.
