Alla faccia del po' di errori

Dear sir,

last thursday i had the opportunity to meet you and your manager, for a tecnical (?) interview.
I (had) really appreciated the way you welcomed me and, at the same time, the seriousness of your company. On my side I am really willing to join your team.
May I ask if you have arrived to a final decision about my application?

Thank you in advance for your consideration.

Best regards,

Amodio

In ogni caso, se hai fatto il colloquio giovedí non gli romperei l'anima cosí presto. Magari stanno valutando altri candidati e ci mettono un paio di settimane.
