FYI, as I have to choose between several internships, I sent them an email in order to know whether the process was still running and they answered:
"Thank you for your email. Our selection process is currently underway.
Please note that the timelines on our website indicates the following:
Final Selection --> Selected candidates: Notification to candidates in October 2013.
--> Non-selected candidates: Notification to candidates in October 2013."
Maybe several divisions are late in the selection process compared to others?
