Your essay is very weak.
Your first few lines are boring, and relatively poorly writtnen.
You do not make it personal at all.
because everybody wants to grow and reach a particular destination and I want to become an IT manager
^There is no point generalizing about other people if you are trying to write a personal statement about yourself.
You do not even say why you yourself want to become an IT manager, which forwards the impression you do not know, and that you are not serious enough of a candidate.
Delft has a wide mix of cultures, usually tolerant to foreigners, and respects the freedom to have different opinions and beliefs. They encourage individual ideas and the educational system has a good reputation. Accredited qualifications obtained from Delft University of Technology are recognized in most parts of the world.
^Usually tolerant? That is insulting to Delft because you are saying that there are times in which they are not tolerant.
What encourages individual ideas?
Good reputation? How? In terms of what?
Recognized in most parts of the world? Thats offensive as well.
Basically,
Your essay is bad. You need to work on it.
