Did not make it this far - canceled before interivew. However the study materials sent to me by the recruiter included basic comp sci/SE data structures and algorithms, that I would need to code in a scripting language during the tech screen. The resources were great, very comprehensive, but so much that it would be best to pare down to the essentials. I learned a lot from looking up what other successful candidates had done for their prep. AlgoExpert was my favorite resource, along with books like Cracking the Coding Interview by Gayle Laakmann McDowell and some popular textbooks.
