I applied through an employee referral. The process took 5 weeks. I interviewed at Yelp (San Francisco, CA) in Jan 2014
Interview
A brief phone screening interview, and then a video interview with technical questions via Skype, and then they fly you out to SF to interview with 4 engineers. All in all, it wasn't really that difficult, and they didn't seem to mind that much if you fumbled here and there with the technical questions. As I was applying for a web dev job, about half of the questions were data structures questions, and then half were web dev questions.

Question 1
Implement a cache (had growing requirements, such as a limit on how many things could be stored in it, and should return the most recently placed record). The interviewer didn't seem to care that I was correct, but more how I approached it.

I applied online. I interviewed at Yelp in Aug 2019
Interview
First I was given a fairly simple hacker rank question to be completed in 20 minutes. Then the next step was to complete a 45 minute video interview over coderpad. The first time the call was scheduled, they sent me a faulty coderpad link, so I had to reschedule it. The second time the call was scheduled, my interviewer didn't show up. Overall I don't know what it is, but terrible interview experience that just wasted my time.

Question 1
The hacker rank was a pretty easy string/json parsing question.
