The HR Person is the gateway of course so through an initial phone interview, she asks you questions to gain insight on you and what skills you bring to table. This is a customer facing role soni am sure she was also interested in my communication skills. A face to face is scheduled with the hiring manager and peer manager for more of the same. The team leads ask you about your skills and technical knowledge. They may even do a basic test. I did not get tested on my SQL skills by creating a simple query but I hear others have. You may even meet with the senior manager and director but I did not.
