A good final formulation should not contain more than three short sentences. This contains four pieces of information in the maximum variant:

• What good is it for the HR manager to invite the candidate?
• When will this be available for the exercise of the activity?
• A statement that shows the interest in a personal interview:

Examples:

• I look forward to positive feedback from you and the opportunity to introduce myself to you personally.
• I look forward to a positive answer from you.
• I am eagerly awaiting your answer and look forward to a conversation in which we can discuss further questions.
• As you can see, I have the necessary skills and motivation. If you are interested in my profile, I look forward to a suggested appointment for a personal interview.
