1. 3Sum variant - find pair that sums closest to 0 2. Systems Design - Design smart meter system for residential complex 3. Behavioral - standard STAR interview questions that focus on your past work experience. 4. Case Study - Mix of technical/business material. Honestly this is a piece of cake if you can debug code and provide improvements to a basic level. I was most scared of the case study because I didn't know what to expect. But basically some things that are wrong with the code are incorrect looping conditions, using poor data type (e.g. when running a loop 10 times they use a long data type vs an int - you can suggest an int to save on memory), and analyzing how methods would run depending on varying input being based in.
