Pros
It is a case study of 'what not to do' hence there is a lot to learn. You learn that talk and socializing is of prime importance and ability is secondary. There is a lot to learn about favoritism and politics. You learn how to play the game. Teams (Trade, Field) can act as they want to deliver results. Things have changed from 5 years ago with a high turnover rate seeing university graduates filling positions and if you are ear-marked to succeed by management through schmoozing, you will go up the chain.
Kontras
1. Politics - understand that all orgs have it but BAT AU is an extreme case 2. HR - powerful lobby that can make or break your career 3. The use of "well, that's how it is done in BAT" to answer anything that may be unjust 4. Aggressive and go-getter behaviour is encouraged at the detriment of individuality. You need to fit a mold 5. Old school management style that appeases the top bosses at the detriment of business 6. Rude behavior - again, accepted at BAT since it is good to drive people to succeed 7. No one wants to speak about products that are launched that don't succeed
