Waiting to hear back after interview

[EaglesWings21, ASN, RN]

Hello all. I went on a job interview a while back and have been in contact with the hiring manager since. My status says open when I log in to see the jobs that I have applied for. I know for a fact that the hospital has had job cuts in the administrative departments due to news coverage on the situation. I am just wondering what is your opinion on how often to follow up. I did send a thank you email, and a follow up just over a week after she said the decision was going to be made. I also sent an email about 4 weeks ago and the only response was that they did not have a decision at the moment. Since my status is still open and I would love to work on this unit would it be appropriate to follow up by email every 3-4 weeks until they decide what to do with this position? Thank you in advance for your input.
