It's been more than a month since I applied to a position in this COVID-era, I've been persistent in my follow-ups with HR (waiting at least one week before sending a reminder), and I've still not received any confirmation of the position, apart from a few questions including this. My application status has always been Under Review.
I've been following up with only one particular person (which is why I believe I may come off as annoying) and my communication mediums have always been emails, and calls to initiate a quick response.
Assuming that nobody is obligated to respond to my request, for how long is it ethical for me to keep following up on this position?
