You know, Penn has a MCIT program in the Engineering dept that has a core boot camp of 6 courses that put you through the basic CS components of architecture/operative systems, data structures/algorithms, basic and advanced programming sort of what most MS will expect of undergrads at bare minimum. Then you take the rest of classes with the general population in MSE. I didn’t see data science but they have machine learning group. But it seems to be for ppl with even less CS classes than you and the others are told to apply MSE. You seem to be neither fish nor fowl.
I just read a first person article that characterized the Berkeley data science program as ‘disappointingly easy’
