AT&T CSR interview questions

Filled out application, did assessment & was immediately sent out an email & texts to reply back to schedule an interview. Both email & text options had technical issues on their end and still have been unable to schedule the interview due to “no time slots available, check back often as availability is updated frequently “ ( this is going on 4 days now) that I’ve been trying to schedule an interview. They actually deal with another company to do the hiring process & they can’t give you any information to reach out to the actual company.
