I applied through an employee referral. The process took 3 months. I interviewed at AT&T in June 2024
Interview
3 rounds, all conducted online. Technical / case questions in all interviews, and behavioral questions in 2 interviews. Difficult questions, but enjoyable process. Excel test and Presentation were required as well.

Question 1
What is the annual gross margin that AT&T makes on Samsung smartphones in the USA?
I applied online. I interviewed at AT&T (Dallas, TX)
Interview
- first round 1 hour phone call with case, not very hard just market sizing
- second round 1.5 hours, excel test (harder than I expected), case (not that hard), and a powerpoint presentation
The whole process seemed very lengthy - several rounds of behavioral, case, and Excel interviews without any clear structure. The Excel interview required several hours for analysis as well as the creation of a PPT, which was then meant to be presented to leadership. Seemed like free analysis.
