Expected Wait Time to Hear Back from Company after Final Interview

I am a new graduate in CS, I've been looking for a full time employment since September. Last week I interviewed at a mid size company (400 people ish) for a role, it was the first time that I interviewed up until the last round where I was interviewed for 3 hours by 6 different members of the team. I feel pretty confident and personally think I had a great interview. Since this was the first time I had gotten through all the interview rounds, I am a little anxious waiting on the decision.

From those who have interviewed in the past, I know it is different from a company to company basis, but what is the expected wait time from the final round of interviews to hear back from a company regarding a decision.

Thank You
