Me postulé a través de una recomendación de un empleado. El proceso tomó 3 semanas. Acudí a una entrevista en Two Sigma (Londres, Inglaterra) en abr 2016
Entrevista
Contacted via Linked in, by their HR.
Call with HR,
Then online hacker rank test (6 questions or so)
Then phone interview. The phone interview was originally missed by them (for some reason they were unable to dial internationally - even though the HR dept had no trouble,) then on the rescheduled day it was 15 minutes late. The interviewer was poor, questions asked were highly specific and interviewer was unable to work out what level of knowledge I had of the topics asked, other than the specific question he was asking (i.e the question on mergesort/quicksort, focused solely on complexity & worse case performance, which I hadn't revised (interview rust), but he could have asked how they work and I could have described them.) Further more, he skipped questions if I didn't answer instantly, couldn't pronounce Design Pattern correctly (so over an international line I couldn't understand what he was asking..) and as I said before wasn't able to elaborate on the questions (i.e he could have said something like explain what a Factory pattern is) instead he just skipped it. One of the worst interviewers I've ever had.
To this day, I've not even heard from the HR department, which I find rather rude.
first interview was 60 minutes long with a leetcode hard question. second interview was 2 back to back 60 minute leetcode hard with emphasis on data structures. each interview had a 5 minute introduction and 10 minute at the end to ask questions

Entrevista
Standard medium difficulty hackerrank. The question involved decoded an encoded string. It was not something I had seen on LeetCode before and I think was unique to the company. The question was not that difficult but I ran out of time right before I could finish answering.

Decode a string encoded using a specific encoding algorithm.
It started of with one phone screen, then if you pass you have 2 back to back technicals, then 3 1 hour behaviorals, hiring committee, and management committee. Standard Leetcode and behavioral questions.
