To inquire about the status of an application from a recruiter, it is advisable to send a polite and concise follow-up email. Start by expressing appreciation for their time and consideration, then politely ask if there have been any updates regarding the application process or the status of your application. Include relevant details such as the position applied for and the date of submission to help the recruiter locate your file efficiently. This proactive approach demonstrates your continued interest and professionalism in the hiring process.
