I applied through a staffing agency. I interviewed at GitHub in May 2022
Interview
An interview with an RH, that was super rude and did not care about the actual candidate, then a Codility test, then they have replied with the standard bye e-mail.
Interview questions [1]
Question 1
You get a string with operation as input:
if it is a number push it to stack
if it is "DUP", then duplicate the one one top and push it to the stack
if it is "POP" then remove the one on top
if it is "+" add the two numbers on top of the stack and replace both with the result of the addition
if it is "-" then minus the two numbers on top (the second minus the first) of the stack and replace both with the result of the subtraction
if an error occurs, e.g. not enough numbers to add/subtract/pop, then return -1
Examples:
Input: "3 DUP 5 - -"
Output: -1
Input: "13 DUP 4 POP 5 DUP + DUP + -"
Output: 7
Input: "5 6 + -"
Output: -1
I applied online. The process took 5 days. I interviewed at GitHub (London, England) in Sep 2025
Interview
First stage recruiter call (45 minutes) which went well, both sides confirmed we'd like to progress to the next stage and the process was outlined. I was subsequently ghosted for 8 weeks, only getting a response when I emailed saying I'd withdrawn my application - to tell me that the team was being "rethought" and the job may not actually be available anymore but they'll let me know (they never did).
