Generally, it takes between a week or two to hear back from Amazon. Also, if you don’t make it past a stage during your application, the company will let you know accordingly. However, it might happen that you won’t hear from the company at all. In this case, it’s advisable that you focus on your applications to other companies.
Understand that many people apply to the company, and it helps that you widen your options across different companies. This way, you always have something to fall back on.
If the company reaches out and you’re to proceed to the next stage, prepare accordingly and get ready. It’s important for you to be on your feet all through the application process. This will ensure you’re not taken aback by any message from the company at any point in time.
