I could consider my one summer internship an integration of sorts. I was in charge of designing a website with Google Maps API, and eventually we would have to integrate it with external data coming in through another website. The biggest issue at the time was finding a programming language that would allow for both the processing of the external data and the functioning website. This turned out to be quite the challenge and in the end we got the individual parts to work but were unable to properly integrate them. When we had to present our project in the end, we had to basically fudge some data. I think if there was better management of time throughout the length of the project, it would have been finished in time.
