I will not give away the interview questions since I've signed the NDA. However, the advises I can offer is: 1: make sure you are FULLY prepared before you attend the interview, they are not EASY. by FULLY prepared, I mean, do a very serious review on your data structures and algorithms! 2: Never begin solve the question before you completely understand what the question is asking. most of the time the interviewer's instruction maybe misleading, not quite accurate or hard to follow. If that happens, do not be afraid to ask for clarifications. 3: Try an example after you write your code. remember to take care of boundary cases such as empty array or null pointer exceptions 4: If you prefer working alone, let your interviewer know, they can let you working alone and come back, or they will try their best not staring at you. 5: Be FULLY PREPARED and good luck!
