UBS is a global, integrated investment services firm that offers a
range of investment, trading and risk management services. I have to
answer the question: "In your view what makes UBS successful", so I
need information about their current and past activities, the relative
success of these and why it's different from other firms and whatever
else you think is necessary in answering the question.

Thanks

HAHA! This is the qustion millions of new recruits have to answer all the time.
The process is quite challenging, so researching yourself will
definitely help you increase your chances of being employed by them.
