AT&T

They have more rounds of interviews, like HackerRank and then a Teams interview with onsite and offshore. After all the interview process, they didn't give any feedback. It's a bit difficult to have multiple rounds of interviews.

Slow pace between different rounds of interviews, weeks even. Ultimately, I received an offer, but I had already signed with another job by then. The process was otherwise mindful and also appropriate for the role.

First, a phone call, then face-to-face. Then, a meeting to meet the team and answer any questions they might have for you. At the same time, answer questions you might have about the responsibilities.
