When to use it
Use it when you get an offer by phone or email. Say you're excited, then ask for a few days to review the full offer. Asking for time is normal, and it gives you room to look at the details and negotiate if needed.
Example
Recruiter: “We'd like to offer you the role.”
You: “Thank you, I'm excited. Can I have until Thursday to review the full offer?”
Recruiter: “Of course.”
In an email or Slack message
By email: “Thank you for the offer. I'm excited about the role. Could I have until Thursday to review the full details? I'll come back to you by end of day.”
