Re Chapfo
People that I met during my 1A were mostly doing 1A so I didn't encounter anyone doing stage 2. I did have someone that told me there would be mostly non-tech, but he did it a year ago, and the letter that I received stated that it was a "Technical and personal interview". in stage 1b...
I was thinking that the schedule of the interview might've changed so I decided to study hard on technical stuff . Also I was browsing through this thread and barely saw people post stuff about 1b until recently there was a couple of them.
