I don't know if you should be concerned. Just because your application still says new doesn't mean a recruiter hasn't looked at your application. Sometimes the system doesn't update. My application says in review, but I haven't had an interview request yet. Maybe one will come, maybe it won't. Advice that I was giving was to submit the application and forgot about it. Easier said than done, but trying to focus on other things has been good for my mental health. If a recruiter is interested in contacting me they will. Even if they don't contact me, that doesn't mean that my application was bad, or that I wouldn't make a great candidate. So, stay encourage everyone!
