@OG2:
There are different dates
Some on the 22nd,23rd,26th and 27th is the last i heared of
and some of the days have more than 1 time like the 27th
For those asking about preparations it was proven by the previous applicants that there is nothing you could prepare for as they are trying to measure your skills levels through 6 aptitude tests that you don't even know what are they and they said in the invitation email that their policy is that they won't tell you what are they
So the only advice I got from the 2 previous topics with 1000+ posts is to sleep well the night of the assessment
Good Luck Everybody
