It is, as Portuguese it surprised me a lot.

First of all, in southern countries we hardly do recommendation letters, if we do they usually ended up being written by ourselves and if the company agrees with the content, it gets signed.

Exactly because of this, you are supposed to give referrals that then talk whatever they feel like about the experience working with you was all about.

Having a whole legal process for recommendation letters, that have created a whole industry of hidden language that looks good on the surface but tells exactly otherwise, was a surprise to me.
