If you were prompted during your text conversation to submit a resume via email, you should have received an email with a unique sender address (e.g. ABCDE@resumes.allyo.com). Please ensure you respond by attaching your resume directly to this email.
Note: Do not attach your resume by responding to your interview confirmation email. Doing so may result in the hiring manager not properly receiving it, and your application may not be considered.
If you have not been prompted and simply wish to pass a copy of your resume along to the hiring manager, make sure you are sending it directly to their email. Their email may be found cc'd in the confirmation email that was sent to you when you set up your interview.
