I applied through a recruiter. I interviewed at Yelp in Jun 2016
Interview
There are three levels. The first level is online coding exam, second is skype interview and third is in-person interview. Coding is easy. Skype interview was mostly about your experience and expertise.
Interview questions [3]
Question 1
List the strings that are anagrams from a set of strings?
Given a list of stock prices brought over a period of time. Find the max loss that could be possible among the data. Ex. [9,2,10] --> max loss is when brought for 9 and sold for 2.
I applied through an employee referral. The process took 3 months. I interviewed at Yelp (San Francisco, CA) in Feb 2016
Interview
The process starts with a basic phone screen to check your background and why you want to work for the company. You get a fairly short take home from Hacker Rank and a skype call to check your coding ability. Lastly you get the on-site interview. They bring you in and have a fellow Yelper eat lunch with you and chat. Sometimes they will have a 1 hour seminar on a random thing someone wants to lecture about in the company (I've heard it can be about wine tasting, astronomy, etc.) and mine was on Tableau software. The process has you do 4 1-hour interviews with white boarding. If you're a fairly strong coder with some knowledge on machine learning and algorithms you should do fine during the process.

Question 1
Coding / algorithm questions tying into something you would see on the job (spam team, search team, etc)
I applied through university. The process took 3 months. I interviewed at Yelp (Providence, RI) in Feb 2016
Interview
The interviewer is from spam group, so all the questions are related to how to detect spams. Mainly basic machine learning concepts covering deriving features, building simple models, short answered technical questions, and finally there is a coding question, which is about given a n by n matrix, finding the minimal cost from the top left corner to the right bottom corner, the follow-up question is instead of finding just the cost, you are asked to find out the path.
