When to use it
Use it when the interview is wrapping up. Say plainly that you want the job, then ask about next steps. You leave on a confident note and know what to expect, so you're not guessing about when to follow up.
Example
Interviewer: “That's all from me.”
You: “I'm excited about this role. What are the next steps?”
Interviewer: “We'll be in touch within a week.”
In an email or Slack message
Repeat your interest in the thank-you note: “I'm excited about this role and look forward to hearing about next steps.”
