There is often some confusion between the usage of 'like' and 'as'.
'Like' is used before a noun or pronoun to say that two things are similar; they behave or work in the same way:
He works like a slave.
She swims like a fish.
He runs like the wind.
'As' is used before a noun or pronoun to refer to jobs or functions:
He works as an accountant.
He works for the company as a trainer.
He is well known as a writer.
Compare these two sentences:
I am your friend and as your friend I advise you to be cautious. = It is my job/role (as a friend) to warn you. OR Because I am your friend...
I think that you and I are like brothers so l advise you to be cautious.
= I am not your brother but we behave in this way to each other.
