1. Someone from C-level will ask this question - Organize all my photos. Things he is looking for to keep in mind - How many pictures? Why do I want to organize them now? How do the pictures make him feel? Key thing - ask a lot of questions and be very very clear. It can make or break the interview. Additionally you only have 5 mins, so you better come prepared for the interview. 2. Someone from engineering will ask questions about designing APIs. Make sure to ask a lot of questions about the requirements, also know how to design REST APIs. Its specifically around how Paxos internals work - exchanges, wallets etc. Additionally, remember to do a SDI with load balancers etc. Would highly recommend using Grokking the System design for this part of the interview. 3. Someone. from product will ask the following question - A paxos partner is launching with bitcoin. This partner is using Paxos behind the scenes. The PM now wants to launch with litecoin. How to handle this case. Things to mention - is litecoin available in the exchange? estimate for how long it will take. MVP launches. etc.

Sort a list of file by names, that has numbers in them. Sort a list of files like: "file1" "file10" "file2" in the correct order: String length -> Number precedence So actual list needs to be "file1" "file2" "file10" There was catch IIRC with ordering "file10" after "file2" since the nature of the numbers. But default string sort won't catch that and do the other way around. So you need to code the correct way for that. Also there is a catch right after with "file01".
