It's not enough to know academic answers, you have to be able to code. In addition to challenging questions (both problem solving and the personality question), you will be expected to code.

This process was for a mid-level position: Initially, I had to complete a written test which included very basic questions on Java as well as a logical critical thinking question. Next I was asked to complete a 130 minute online java test which included 3 different problems that included an algorithm problem where time complexity did not matter, another algorithm problem where time complexity did matter, and a question that essentially tested your debugging skills. The next step was an on-site technical interview with three senior engineers. They asked many questions that tested both basic concepts of Java (in a tricky way) as well as some nuances of the language. They also asked you to perform a code review on some java code as well as write a bit of code. The final step is another on-site interview with more of the team and managers. This was to make sure you be a good fit personality wise.
