Albert Barnes Commentary Esther 2:11

"And Mordecai walked every day before the court of the women`s house, to know how Esther did, and what would become of her." — Esther 2:11 (ASV)

Mordecai occupied, apparently, a humble place in the royal household. He was probably one of the porters or doorkeepers at the main entrance to the palace (Esther 2:21).
