A recruiter reached out to me, said TripAdvisor would be interested in my profile and, in case things go well, sponsor a working visa (I am not a US citizen). I had a technical interview on Skype with a Technical Manager. He made me feel extremely comfortable during the whole call. He first asked me why I wanted to join the company, then wanted to know more about my previous job as Data Scientist. Theoretical question: Hash Table and its complexity. Practical questions (answered on shared, real-time text editor): Intersect two sorted arrays/lists; Linked List + Fibonacci indexes. For each solution I was asked the complexity of it. Pro: it is possible to choose between many programming languages, such as Java, Python, JS, … Unfortunately, I kinda screwed up the Fibonacci question. Everything was quite easy. Anyways, it's been 20 days since I was interviewed, haven't received any news neither by the recruiter, nor the company.

Question 1

// Given a singly linked list without values defined by: class Node { Node next } // Write a function that removes all elements from the list whose _index_ is a fibonacci number // o -> o -> o -> o -> o -> o -> o -> o -> o -> o -> o -> o // 0 1 2 3 4 5 6 7 8 9 10 11 // x x x x x // becomes // o ----------------> o ------> o -> o ------> o -> o -> o // 0 4 6 7 9 10 11

Question 2

# Q1: Write a function to intersect two *sorted* lists (find common elements) # Write a method taking two lists as input, and returning a new list # You can assume you have a reasonable array/list class available (ArrayList, vector, python list, etc) # Ex: # l1 = [1,2,3,4,5] # l2 = [1,5,7,11,100] # result = [1,5]

Question 3

# Q2: Same as Q1, but now assume there can be duplicates. The output should not have duplicates # Ex: # l1 = [1,2,3,4,5,5,5] # l2 = [1,5,7,11,100] # result = [1,5]
