After final interview, no one replied to my thank you email. Is this normal or does it mean something?

UPDATE: I didn't get the job...

I had a final interview this Wednesday. After several rounds of interviews, I finally got invited to fly out to their city for the final interview.

I had coffee with teammates - had super fun, one of them even gave me handwritten notes of thank you for interviewing with them. Had lunch with directors. And I got starbucks giftcard from one of them for lunar new year. And had a final interview with directors&VP including office tour. It was quite intense one and a half hour interview but I guess it went well.

Everything looked like good signs until I sent out thank you email to HR and hiring manager and both of them don't reply.... Does this mean something? Or am I overthinking this? Please let me know..

They told me I will hear back early next week but this weekend feels like forever 😭 Especially when my visa will expire soon so most likely this will be my chance...
