PepSinger_PT's journey

I submitted an application for a position three weeks ago and I'm starting to wonder about the timeline for hearing back. I'm looking for insights on how long it typically takes from application to contract signing or starting the job. I've only applied to this one job so far, and I'm curious if three weeks is a normal wait time or if I should be concerned. I've seen mixed experiences from others, with some saying three weeks is not unusual, while others mentioned that if you haven't heard back by then, it might not be a good sign. I'm in the US, so I'm hoping to get some clarity on what to expect.
