I applied online. I interviewed at AT&T (Seattle, WA) in Dec 2024
Interview
The interview asked serveral questions about your experience of using ML algorithm. And BQ questions like how you collaborate with your teammates. What is the most challenge thing in the project and how you fix it. No concret techical problem. I don't think they know a lot about ML knowlege.

After I applied, the first round was an automated HackerRank OA, which had four questions with a 1 hour limit. The first two were standard questions and then one basic SQL question.
