looking for a job

I'm finishing (1) the college (2) and then I'm looking for a job. Nowadays, (1) the companys are too demanding. (1) The people (3) have to be being a (4)heros , (5) speaking three or four (6)fluency languages fluently, be organized, punctual, level-headed and manage people(7)  , .
I hope (8) to get a job soon. I want to learn more and improve my skills (9) .

Sou falante de inglês, mas tento português primeiro.

I will switch between English and Portuguese.

1) primeira coisa em inglês, não usa um artigo para o nome geral ou seja, quando deseja falar sobre uma empressa especifica, usa "the" ou "this" ou "that".  It is not wrong but article use (the is used for emphasis or to point out a specific, for example.  I would talk about the companies in São Paulo are too demanding, but I would not say "the companies" without being specific.

2) Tem dois frases aqui.  Se liga, usa "and".  Se não liga, usa "periodo".  You have two phrases here, your choice is link them using "and" or keep them seperate with a period.

3) Deve usar o infinitivo com "have". When you use the verb have as a helper to indicate a requirement (like "ter de/que") you must use the infinitive and not the gerund.

4) Escolha de palavra, heroi não justa aqui.  Hero is not the right word, you might use "super hero" as hyperbole or exceptional. 

5) Ten de usar o verbo infinitivo porquê a situação de notação 3.  You must use the same verb construction in the sentence, i.e if you start with your verb as a gerund then stay with the gerund.  If you use the infinitive continue with the infinitive.

6)  Escolha de palavra, "fluency" é um nome, mas "fluently" é um adverbio. Fluency is a noun, fluently is an adverb.  Sidebar all words that end in "ly" are adverbs, but not vice versa.

7) Comma indica um série.  You ended the thought, use a period.

8) infinitivo

9) Há um espaço entre última palavra e periodo.  There is a space between the last word and the period.
