There is a chance that the wait is longer because you would be in the next (later) training class block. People who applied in Dec. or Jan. and are now up for an April class had a pretty long wait between initial application and the first contact/email. (3 weeks for me.)
This quote comes from an email my recruiter sent me after my first phone interview, but I think it applies:
"We are in the process of finalizing the interview schedule for our Team Managers. Once our interview block is complete, we will follow up with the link for you to go online and select a time to interview. ...We apologize in the delay to schedule your interview."
To me, that sounded like they had more interviews to do than available interviewing Team Managers. It was comforting to know, in that position. Maybe it will make you a little less anxious...?
