Applied at Nvidia for HPC Engineer

I recently completed a final panel interview for an HPC Engineer position at Nvidia. I'm now in the waiting phase and wondering how long it typically takes for them to get back with a decision. I've heard from others that it can take about 1-2 weeks, but I know some companies can take longer. I'm considering sending a polite follow-up email after a week if I don't hear anything, just to express my continued interest without being too pushy.
