When it comes to GM team, as a rule of thumb, you can ask for a feedback from any GMs two weeks after sending your app.
This rule does not apply during recruitment drive, simply because the whole process of voting takes a lot of time and we're picking apps from the best. During recruitment drives, most GMs are swamped with apps and most of them might get rejected without much reasoning just because they're objectively worse than others (pay attention to grammar and punctuation, have a clear structure, and try to stay polite, and you should be good to go), so you might not get a straight answer right away.
Any questions about the apps during recruitment drive will be answered when possible, but expect a little bit of radio silence.
As a sidenote, please don't spam GMs or contact them too frequently about your application, it tends to be a bothersome and doesn't really inspire confidence. It's okay to ask, it's not okay to keep asking for days.
