Interview first started off with a 30 question multiple choice test. Each question was timed for 2 minutes each and ranged from OS to Recursion. Some questions were simply, explain why this code does not work to fill in the line of code that makes this work. Ultimately, the questions were used to test your range of knowledge but found it rather unpleasant given why it would want a Full Stack Engineer need to know the difference between things like program counter and branch prediction. The questions ranged in several different programming languages like Ruby on Rails, JavaScript, Python, C++, etc. Overall, I thought the interviewing questions were too broad to judge a potentially good candidate which is why I'm a little disappointed in their interviewing methods. Either you knew the answer or you didn't. There was no time to deduce an answer with the limited time for each question.
