Brain teaser: You have nine coins that are identical in weight except for one which is lighter than the others. The difference is perceptible by weighing them on a scale, and only the coins themselves may be weighed. How can you identify the lighter coin in the least amount of weighings?
Many behavioral questions

If i give you a sphere and assume that you don't have any equipment like EDS to characterize the sphere, How can you determine what material it's made of?
What is the complexity of the Quick Sort algorithm?
You must pass the online test before moving on to the next step. It is not extremely difficult, but you have to possess good knowledge of probabablity, statistics, & quantitative. You have 1 to 15 minutes to answer a question depending on the difficulty, thus you must be able to solve the probably immediately, no time to research online. Given the time constraint, the difficult part is that you MUST use math on a regular basis & remember which formulas to use. That was my problem, haven't used these tools for quite some time. I was pretty good at Math (top 1% for SAT & GRE), but I didn't pass the online test :-( The interview could have been more well-rounded by giving the candidates more chance to present their capabilities beyond the online test result.
