When, typically, are the classes held? I confirmed with HR before accepting an invitation to interview that while they are looking for winter 2018 right now, I would be unavailable until May 2018. I was informed
You could begin the application process now, and then if you were offered a class date it can be at a later slot
However, I do know that they would not likely hold classes in the summer because that is the busy season. My hope was a class in early May as soon as I graduate, but I'm afraid of not getting one until next October or worse.
