I just wanted to tell you what a wonderful experience it has been to work with the IM CORE team. They have been responsive from the beginning addressing our questions and concerns in a timely manner and being very efficient with the hiring process from posting JOAs, issuing certs and extending TJOs. And they have kept us updated the whole time, which is truly appreciated. Having previously worked as a HR Specialist I know the volume of the workload that the team is dealing with and I appreciate everything that the IM CORE team has done to move our hiring actions forward. I just wanted to say Thank you to you and the team.
