Report back cover letter

Respected Mr. Arnold, I am writing this letter because I have attended an interview call by your company and was interviewed by you, hope you remember me. Honestly expressing my view towards that interview, I felt very nervous before I entered the room, but once I took the hot seat, I really felt comfortable which I must say was because of your splendid and supportive behavior. I am very much thankful to you for making me forget my tensions and paving me a way to perform my best. My intension of writing this letter is that I have forgotten to mention my salary expectation on the day of interview; I am not very much concerned about the salary and anything above or equal $40 k per month is acceptable to me. The main requirement I request from you is that, please give me the development side, ensuring me a scope to grow. Thanking you. John
