Product specialist interview questions shared by candidates
You have 2 beakers, one that is 3L big, and the other being 5L. You have a bucket which you must fill to exactly 4L, and you must use these 2 beakers to get to that goal. You can fill and empty the beakers as many times as you want in order to get the 4L in the bucket. You cannot take water out of the bucket after you have filled it.
You have 3 bags of marbles; one filled with Red marbles, one with green, and the third containing a mixture of the two. They are all labelled with either Red/Green/Mixed, except all the labels are wrong. How many marbles would you need to take out to determine what marbles are in each bag, and why?
