I applied online. The process took 2 months. I interviewed at AT&T in Jan 2019
Interview
Interview was a mix of emails, one way phone interview and and questionnaires. You spent a lot of time waiting and taking them. Some logic tests. Overall nothing was super challenging, but mostly took up a lot of your time to not get many answers. As to be expected for a large company.
Managers give you a glimpse of the job and feed you all the nasty of the job to get you to step down. Once deciding to proceed you get a very straight forward behavioral based interview.
Starts with a session where they introduce the company and role. After the group session, there's individual Interviews with a manager. They focused on customer service, solving problems in a work environment, and other behavioral questions
The gave me a tour of the whole place, They explained some of the tasks that will have to be done, and asked some basic questions at the end , i asked when he would get back to me but he said he had no idea
