Well, from my group of around 20 we went in 16 so... Sorry to hear that you did not.
I have a doubt, you talk about the sim. As you know, to get to the sim you need to have the OK from the english test and the HTA (psychologist, 5 hours... pretty hard as you said). So, I assume that if you were kicked out of the procedure after the sim was because of the sim. Simple.
I have a close friend that failed this week after the HTA, he was not able to attend the sim as he was told to go home after the HTA. So, what is your point? You blame only the HR representative and the psychologist because of the HTA but apparently you did not pass the sim, which is another thing.
Just curious.
