Making a false statement on the resume would be haram. However, one an be creative and state one’s experience in a way that is more effective. Now if you technically have done 6 months of work that’s related to your field (even though it’s not directly about the job you are seeking), then you can list that since it’s not a false statement. So the key is not to give a false statement, but you can be creative in making your resume more impressive.
