Is it appropriate to follow up on a job application?
Yes, it is appropriate to follow up on your application if you haven't heard back from the employer.
Job searching can be frustrating, and not hearing anything back doesn't necessarily mean your application wasn't successful. However, it's important to be mindful of the closing date and any time frames provided by the employer.
If the employer hasn't provided any timeframes, give them a week or two to evaluate applications before following up. You can do this via a short, friendly email or phone call to ask for an update on your application. If you are invited for an interview, be prepared for multiple stages and ask what the next steps are and when you can expect to hear from them.
If you do receive feedback on your application, take it as constructive criticism and learn from it. Being professional and respectful in all interactions with the employer, even if you receive negative comments, will leave a good impression and may help you secure future opportunities.
