Candidate interview experiences
First-hand accounts from people who interviewed at Docker.
Software Engineer
It started with a quick 30-minute recruiter screen, which went fine and covered basic questions and company info. The recruiter also explained the rest of the interview process: three technical interviews with coding exercises, followed by a final non-technical interview with a senior leader. They really emphasized that the coding exercises would be practical, not algorithm or data-structure focused. However, the first technical interview with the hiring manager gave me an algorithm challenge, which was not practical at all. I didn't pass because I don't practice LeetCode. It's a bit disappointing that the recruiter's description of the technical interviews didn't match the actual content, which is something they should probably fix as candidates generally don't like being misled.
- Tell me about your ideal team.
- What kind of company do you envision yourself thriving in?
Software Engineer
I applied online and a recruiter reached out saying my CV was a good match for an intro call. We scheduled it, and during the call, we discussed my reasons for applying to Docker, my current job search, and salary expectations. The recruiter said it was a good match and I'd move to a technical interview. After a few days with no response to my follow-up emails, I assumed the process was over. A month later, I got an automated email stating they couldn't reach me and would consider me not interested. I replied, pointing out they hadn't actually contacted me, but again, received no response.
- What motivated your application to Docker?
Senior Software Engineer
There was a recruiter call first. Then a hiring manager call with a simple coding task. After that, a coding task that was related to the team's actual work but without algorithms. Lastly, a coding/debugging task where I was given a GitHub project to debug, fix, or optimize.
- What are different isPalindrome implementations?
- Do you have experience with simple coding tasks?
- Can you complete a coding task related to the team's actual work without using algorithms?
