AT&T interview questions

Applied online and received OA within a day. After passing the OA, I got an email 2ish weeks after inviting me to an online technical round which was very similar to the OA. Got ghosted afterwards

One of the most embarrassing and truly unprofessional experiences I have ever been through. I went through 3 rounds of interviews including having me come on site (took a PTO day). I was told it was just myself and one other candidate. After the final interview I never heard back from the team. Never in my 35 years of life have I made it through a final interview and never heard back. It's not only rude, it's remarkably unprofessional. You're a recruiter and can't call a final round candidate back to tell him he didn't get the job? I can only image how poorly the department is run when the lead recruiter is afraid of calling candidates. Thankfully I was offered a much better position two weeks later. You should be ashamed of yourselves for the way you treat people. I reached out multiple times just for an update and was ghosted.
