Application Follow-Up Templates

I've applied to jobs and haven't heard back. I want to follow up effectively without being annoying or desperate.

Help me with various follow-up scenarios:
1. Applied online and waiting for a response
2. Had a phone screen, waiting to hear about next steps
3. Completed final round interview, waiting for decision
4. Recruiter went silent after initial conversation
5. Got rejected but want to stay on their radar for future roles

For each scenario, help me:
1. Determine the right timing for follow-up
2. Write a concise, professional message
3. Add value beyond just "checking in"
4. Know when to move on vs. keep following up
5. Handle the emotional aspect of waiting and silence

Ask me about the specific role I'm most anxious about - the company, the position, when we last interacted, and how long it's been. Then help me craft the right message.

I want to show interest without looking desperate.
