sysadmin55's journey

I had a recruiter from the company reach out to me for a role during the week of May 18. I applied right away and was hopeful about the opportunity. However, three weeks later, I received a message from her stating that my application was still under review and that they would update me once they had made a decision about the next steps. This lack of communication has left me feeling uncertain. Is this typical in hiring processes? I’ve heard from others that it can take a long time, but this is the first time I’ve heard from her in weeks. I’m considering sending a polite follow-up soon, but I’m also focusing on other job opportunities in the meantime.
