1) How would you parse a large (60GB) log file into a csv and what language would you use for it. 2) Describe what happens in the browser when a user visits an address. The questions are senior level at most. Also, tip, even though the first question is more of a sysadmin than developer one make sure to answer that you'd use JavaSCript because to them, JavaScript is the best thing since sliced bread. The interviewers felt like they were senior devs with inflated titles. The questions should be easy but they are really look for something very specific and something that they themselves understand.
