Interview
One variation of the candies question is as follows: You have x+y+z=10 piles of candies, and each pile contains candies weighing either 1 g, 2 g, or 4 g. How can you use a digital scale only once to determine which pile contains which type of candy? The other questions are the same as those mentioned in the other posts.

Interview
As soon as I arrived, I was led into the open office, where they gave me a table and laptop with the 4 tests pre-loaded. The office space was pretty quiet with some chatter every now and then. They gave me a visitor pass and then asked to have my phone. During my interview there was another candidate writing the same test right next to me.
