Pros
Professional Startup, not some random startup, but a very professional startup. Every person is well-versed and passionate in what they do, and they all want you to become better. Boss genuinely cares for you to become a better programmer. Location is great, and since it's a startup, you learn so much more than being limited to one field.Best part is that they treat you equally to any other employee.
Cons
Unless your dream was to work at a big N or a larger company, I don't see much downsides to interning here. It is an invaluable experience. Mainly focused in mobile development (not a bad thing)
