[Grammar] result/decision of my application/interview

[uktous]

Hi,

Background:
After my job interview, I want to send a thank you letter to the interviewer.

Question:
Which sentence is the most sensible?

Sentence1:
I look forward to hearing the result of my application.
Sentence2:
I look forward to hearing the decision of my application.
Sentence3:
I look forward to hearing the result of my interview.
Sentence4:
I look forward to hearing the decision of my interview.

Thanks

How about simply 'I look forward t hearing from you'?
