White just completed his 10th season with the Dodgers and fifth as assistant GM in charge of scouting. White oversees the organization's amateur and international scouting efforts and is the fourth known candidate to interview for the job that became vacant when Ed Wade was let go.
White interviewed with the Astros in 2007 prior to Wade's hiring.
Astros president and CEO George Postolos had no comment.
Others known to have interviewed are Rockies senior vice president of scouting and player development/assistant general manager Bill Geivett, Cardinals vice president of player procurement Jeff Luhnow and Royals assistant GM in charge of scouting and player development J.J. Picollo.
The Astros are focused on GM candidates who have a strong track record in scouting and player development as they try to rebuild the club following a 106-loss season.
