Technical screening first round - I was navigated into a Jupyter notebook and asked to complete a series of coding questions for a data analyst role. Questions ranged in difficulty, strong knowledge of pandas was helpful

Went online and applied for a position. About a month later I get an email from AT&T asking if I wanted to do a phone interview. Phone interview was composed of three people on their side of the conversation asking questions. Asked questions about my experience and then listed some options of what I could do as an intern. I chose the "developer" role. Asked about a good number of object-oriented programming questions. They got back to me approximately a week later.
