my suggestion for a programming job:   pick a primary programming language: just like our mother tounge, every programmer should have a primary language to express programming logic. Java - requires atleast 4 weeks ( 20 x 2 hrs) python / php / perl / javascript - requires atleast 2 weeks    learn reading and writing code: This is one of the most important skill. no code will be documented. all that you need is to learn how to read and write legible code.
