Meta Software Engineer interview questions

Made it part the first phone interview, rejected on the technical interview after not knowing the questions. Entire process took about 3-4 weeks, and ran very smoothly. Phone interview lasted 15 minute and the technical interview an hour.

Very nice phone interview. The interviewer was very calm and kept a relaxed atmosphere (no pressure to finish faster and no negative reactions when you get a question wrong).Questions were not very difficult: find all possible permutations for a string and finding an element's position in a slightly sorted array in the most efficient way (you have something like [5,6,7,1,2,3] and you want the position for "2" -> you use binary search algorithm)
