Students can submit a scholarship application anytime before their programs enrollment deadline. Many of the algorithmic concepts tested in coding interviews are not what I usually use at work, where I am a Front End Engineer (web). I would absolutely avoid lower-level languages like C or Go, simply because they lack standard library functions and data structures. When you join the Dojo, youre in the family for life!
