I was asked about my salary expectations, and now I’m on hold for two weeks. Is this a common situation?

I just wrapped up my final interview for a position last Friday, and they mentioned I’d hear back either yesterday or today. They reached out and said:

“As we move forward in the selection process, we’d like to better understand your salary expectations for this role.”

After I provided my salary range, they replied with:

“We are currently reviewing all applications and expect to update you on the status within the next two weeks. If anything changes or if we have additional updates before then, we will be sure to contact you.”

Is this typical? It seems like they might be weighing multiple candidates and using salary as a factor in their decision. What are your thoughts? A friend of mine thinks it might be a sign of price gouging or that I’m the backup candidate.
