3M interview questions

Applied via email and got a response inviting me to take an online ability test. As far as I can remember there was a numerical data section and a critical reasoning section. I got past this stage and was asked for interview at 3M's offices within 8 days. I had to repeat the online test of the same level once I got into the offices. That took about an hour. Then I had a 2 person panel interview which contained the normal marketing/team-working questions. That lasted another hour. It all went quite well. The offices were brand new and well designed. There was a lot of office space for the number of employees I could see. Only thing I would say is that public transport to the location was not good. Dress code throughout was business smart.
