I applied through college or university. I interviewed at OpenTable
Interview
Emailed back and forth to schedule a phone interview. Got a call from a senior Data Scientist that asked me a few related algorithm question. By the end the questions were complicated enough whre it became difficult to describe over the phone. I was able to answer all questions (though I required a hint for one) and he then congratulated me on surviving the ksum question.
Interview questions [1]
Question 1
First question: You have an array of numbers. Find all pairs that add up to K.
Second question: You have an array of numbers. Find all three-element groups that add up to K.
Third question: You have an array of numbers. Find all four-element groups that add up to K.
For all these question I had to provide a running time.
The product seems interesting, but the HR person complained about their work and didn't know how to answer basic questions about the team during the interview. I got a generic rejection a few weeks later.

I applied online. I interviewed at OpenTable (Toronto, ON) in Dec 2025
Interview
It was smooth however they failed to inform what was the nature of the interview. I assumed it to be a screening /behavioral interview but it turned out to be a technical coding interview
I applied through other source. The process took 2 weeks. I interviewed at OpenTable (London, England)
Interview
The interview began with a phone call with hiring manager where my interest to apply and past experiences were gauged . Followed by a take home coding test . After the coding test was submitted , I had three to four rounds of interview speaking to future team mates and one pair programming session related to the coding task , then a chat with the PM , hiring manager and another manager . Although the interview took long it was great experience meeting really great people. The whole process was great and didn't feel like I was being tested but the interview was conducted with an approach of getting to know the candidate
