Avantages
All their courses are free for the interns.
Inconvénients
No stipend.
The courses that you get as a replacement are not useful, low level content.
Your inputs are not going to be considered.
They just simply stick to 1-2 good employee they have and donot think before insulting you.
A very small company useful for initial 1st/ 2nd year student only, if you are above that its merely a waste of time.
