Barcap phone interview

Barclays capital telephone strength based interview questions :

The questions that I can remember are:

1. You organise an event and more people than expected turn up what do you do?
2. What motivates you?
3. How do you motivate others?
4. If you were in a good performing team but thought something could be done better what would you do?
5. Do you like proof reading and paying attention to detail?
6. How to you build friendships or rapport with people?

Actual trading interview questions:

Brain teasers:

Calculate the equivalent interest rate of the following :

Hsbc have an offer whereby they will give you £1,000 up front if you give them £11,000 and after one year you can withdraw your original deposit.

Another brain teaser:

The interviewer asked what is the probability that he could guess my phone number given he couldn't just look at my cv.

Another teaser was just to express the reciprocal of 2x2x2x2x2 as a decimal.
