Step 1: Identify the direct speech.
The direct speech here is: "Are you qualified for the post you applied?"
Step 2: Conversion to indirect speech.
When converting to indirect speech, we need to change the reporting verb (here, "said to" becomes "asked"), adjust the pronouns, and modify the question format. Also, "Are" is changed to "was" as the question is in past tense in indirect speech.
Step 3: Final Conversion.
Thus, the correct indirect narration is: "Narendra asked Pooja if she was qualified for the post she had applied for."
Final Answer: \[ \boxed{\text{Narendra asked Pooja if she was qualified for the post she had applied for.}} \]
