Just had an interview for Santander.
I got asked the following questions:
Why the financial sector? Why Santander? Why this business area? Tell me about a time when you've displayed exceptional customer service. Tell me about a time when you've worked in a team. Tell me a time you had to make a difficult decision
There were the usual follow up questions like:
What did you learn ?
Why was the decision difficult?
What did you have to consider when making the decision?
Hope this helps
