they contact me via email and then said they want to have a short and easy phone screen and i can choose a time slot and then they called me at that time from American and ask me some simple questions and if i can accept the salary.

I got past the initial call and video interview and then progressed to the in person interview in a matter of a week which seemed rather rushed. The in-person interview was fairly standard with the hiring managers being professional and polite. They did bring up some fairly major duties in the interview that weren't on the job spec though a bit sus. Anyway I left feeling like I did well, I then waited 2 1/2 weeks to then receive a generic rejection email. This email was the typical corporate waffle saying due to the early stage of my application I couldn't get any feedback, this obviously was rubbish as they had literally seen me for a final interview?! I sent them an email back being rather nice and asking for some feedback and I wanted to improve on my interview technique and see why I didnt get it etc. I sent this a solid month ago and haven't heard back. I hate to sound bitter as I understand that I might not have been right for the job but this hiring process is impersonal and typifies how frustrating the job hunt is.
