Siemens Energy hiring process — is this a positive sign or just administrative?

I’m currently interviewing for a position at Siemens Energy and would appreciate some perspective from people familiar with large-company hiring processes.

I was apparently referred/sourced from a previous unsuccessful Siemens Energy application, although I don’t know who referred me. I was contacted and went through a phone screening followed by two interviews, with the second being the final interview on July 27.

Four days after the final interview, HR called me twice because I didn’t answer, then emailed me and also contacted me on WhatsApp asking me to apply through the portal. She said: “As part of the process, kindly apply through this link for you to be officially associated with this role.” I applied the same day.

When I asked for an update, she said they were “awaiting feedback from the Hiring Manager.”
The job posting has since closed, but my application still shows “In Progress – Hiring Manager.”

I followed up again on August 10 but haven’t received a response yet.

I’m now about 16 days after the final interview. Does this sound like a normal internal approval/decision delay, or could they still be deciding between finalists? Would the request to formally apply after the final interview usually be a positive sign, or can it simply be administrative?

Any insight from people who have gone through Siemens Energy or similar large-company hiring processes would be appreciated.
