H1B transfer timeline with Google BAL

I recently signed an offer and Google completed the background verification in two days.
BAL reached out for documents and questionnaire : 04/14
I filled the questionnaire and submitted documents : 04/14

My application is listed for Premium Processing. There has been no update since 04/14 on my application. How long does BAL take to file LCA and then file H1B?

Please share your timeline. I need to adjust the time when I inform my team at current job as well based on how this process goes.
