This is a complicated topic that depends on factors with the individual (e.g., self-understanding, stage of transition), company (e.g., acceptance), and general survival (e.g., bills, medical expenses, threat of harm). Seek guidance from your community and do what is within your comfort range.

Note: There are jobs that may conduct screening before you are formally considered for the position. Using your chosen name means you will not show up in background checks or with past employment references. This may greatly impact your ability to move forward in Federal jobs that require a security clearance (or the background check may take far longer than the typical candidate). The good news is that these situations are extremely rare. Most jobs won't do anything requiring a legal name until after a signed job offer.

"It is your decision as to what name to put on your resume. There are many factors to consider when or if to disclose a transgender identity (e.g., legal protection, bigotry). My thoughts: Base your choices on being true to yourself. You will have to give the company your legal name for the job offer and W-2."
