Solicité el puesto a través de un captador. Acudí a una entrevista en AT&T
Entrevista
First part was a hackerrank (all leetcode easy/medium). Second part was an HR phone call. Third part was submitting a project about OOP. Fourth part was a technical interview asking questions about the project + just other general questions. And last round was a HR phone screen.
Everyone was so amazing and the process was pretty quick (around 4-ish weeks)

OOP design principles, data structures + algorithms
Unprofessional. Interviewer kept delaying and rescheduling within the same day. I waited all day to interview. After that, the technical was kind of simple. Asked basic OOP questions and basic style leetcode. Also asked system-design related questions.
