Yes, one of the summer internships here started in August and August, and many of them worked in WPS.
I came in at the end of June (now the training camp is divided into batches at the end of June, July and August) and I have been here for three or four weeks. I feel that if I want to learn C++ and programming ideas, this should be a perfect place to make you feel good. Of course, if you don't want to be a programmer or don't like programming, it's really unreliable to come here. Because I usually contact with those programmers and those codes, and the rest are for myself.
You don't have to worry about not recruiting people. The training camp here implements the elimination system, and many people may have to leave halfway.
