I am very sceptical to hope too much despite the positive signs I received during and after the interview. The recruiter said two things that solidified my thought that I might been chosen for the job already:

1. He said congratulation to me and said I should expect the letter next week.
2. He introduced me to some of the employees over there with the job title that I was interviewing.

But then all of this could be some unserious things he could’ve said as a joke and if that were true, that was very disappointing to me.
