How to Prepare for a Job Interview
Make a good impression at your interview by doing a little homework beforehand.
Research the Company and the Position
The more you know about the company and the job you are applying for, the better you will appear in the interview. An interviewer will be impressed by your interest and motivation, and you will be able to explain what you can do for the company.
Find out as much key information as you can about the company, its products and its customers. If possible, talk to people who work at the company. There may be other sources of information on the Web, especially if the company is publicly traded.
Search for the following:
• Office locations
• Products and services
• Customers
• Competitors
• Philosophy
• History
• Recent news
• Financial info, including salary and stock

Brain Teaser Question
A number of 9 digits has the following properties:
• The number comprising the leftmost two digits is divisible by 2, that comprising the leftmost three digits is divisible by 3, the leftmost four by 4, the leftmost five by 5, and so on for the nine digits of the number i.e. the number formed from the first n digits is divisible by n, 2<=n<=9.
• Each digit in the number is different i.e. no digits are repeated.
• The digit 0 does not occur in the number i.e. it is comprised only of the digits 1-9 in some order.
Find the number.
Answer
The answer is 381654729
One way to solve it is Trial-&-Error. You can make it bit easier as odd positions will always occupy ODD numbers and even positions will always occupy EVEN numbers. Further 5th position will contain 5 as 0 does not occur.

A Interesting puzzle
In a sports contest there were m medals awarded on n successive days (n > 1).
1. On the first day 1 medal and 1/7 of the remaining m - 1 medals were awarded.
2. On the second day 2 medals and 1/7 of the now remaining medals was awarded; and so on.
3. On the nth and last day, the remaining n medals were awarded.
How many days did the contest last, and how many medals were awarded altogether?
Answer
Total 36 medals were awarded and the contest was for 6 days.
On day 1: Medals awarded = (1 + 35/7) = 6 : Remaining 30 medals
On day 2: Medals awarded = (2 + 28/7) = 6 : Remaining 24 medals
On day 3: Medals awarded = (3 + 21/7) = 6 : Remaining 18 medals
On day 4: Medals awarded = (4 + 14/7) = 6 : Remaining 12 medals
On day 5: Medals awarded = (5 +7/7) = 6 : Remaining 6 medals
On day 6: Medals awarded 6
