Puzzle - I have a Mathematical logic in my mind, and I would give you three numbers that satisfy that logic. You cannot ask me questions but can only give me three more numbers to which I would reply ‘yes’ if the numbers satisfy the logic and ‘no’ if they do not. You can ask unlimited number triplets, but you have only one shot in solving the logic. The numbers are 2,4,6. (E.g., If I say 3,6,9, the interviewer will respond as ‘yes’)
The numbers are in ascending order ( The key here is to eliminate all possibilities and not jump to conclusion)

Further, he gave additional problem solving of an e-commerce platform. Bounce rate of an ecommerce website if up by 20%, what do you think is the reason.
Structure is very important here. Be well versed with the e-commerce funnel and which KPIs you will look at to know what is going on. I started by asking the device type questions (Mobile vs Desktop), he said the bounce rate is in mobile app and not website. Further I asked for a trend (as in for how long we see this increment). To this he mentioned that the bounce rate has increased suddenly in one day span. Post this I went into the ecommerce funnel and tried to identify from which page customers were leaving the application. Once that was narrowed down, I asked for has there been any UI changes in this one-day span. It turned out that technical team had done some UI changes because of which few call to action buttons were not visible on the mobile screen (less than 4inch screen).
