AT&T Student Technical Intern interview questions

Very unstructured. Took 3 phone interviews. One with HR, one with an employee in my field, last one with the manager where the offer was given. I was not made aware of what was happening after each interview and ended up with an offer. Pretty good for my first experience with landing a job however I would not have taken it if it wasn't my first job.

The order of interviews: Online technical interview -> Behavioral interview -> Technical Interview + 2 Behavioral Interviews From the online technical interview to the behavioral interview it took about a week to get a reply From the behavioral to the technical + 2 behaviorals took about 2 weeks to get a reply. Then it took another week for the offer to come in
