BAT interview questions

Several weeks after I submitted my CV on their online recruiting page, I was told that I made it to step 2 of the process. Step 2 was a numerical and verbal test (20 minutes each) which were easy but you had to be quick to finish them on time. Step 3 was a competency based phone interview with questions like "tell us about a time when you had to work in a group", "A situation where you had to adapt quickly", " A hard decision you had to make" etc.. and why I wanted to work for their company. Step 4 was an assessment center which actually took place in another country (candidates were screened for similar positions in other countries too). To be honest the people there (there were HR people but also from other departments such as marketing and finance) did not strike me as anything special. We, the candidates, had dinner with them the night before in order to get to know them before the assessment day. All of them were very happy with their work and very enthusiastic but they did not strike me as very intelligent or interesting. Oh, and none of them had any ethical issues tied to the nature of the business of their company.
