“I am very grateful for the assistance Frank has given me. This is the first time I have worked with recruiters. While I would like to say something along the lines of, “and I have found my forever job,” which may be true, realistically I anticipate more opportunities to gain knowledge, experience and growth at some point in the future. I will likely contact your company at that time. Frank has been so easy to work with and accommodating. In fact, encouraging would be a good word to use as well. Many, MANY, “firsts,” for me.”
