Site Reliability Engineer Interview

Anonymous Interview Candidate in London, England (UK)
No Offer
Positive Experience
Difficult Interview


I applied through a staffing agency. I interviewed at Duedil (London, England (UK)) in August 2017.


I was approached by an agency recruiting for this position. The first stage was an initial screening and discussion about the career progress. Afterwards, I was asked to fill in a test of 20 questions regarding Linux, Bash Scripting and Python. Having provided the satisfactory answers I was given an assessment task to complete at home. Eventually, I was invited to DueDil's office for an interview lasting 3 hours when I spoke to 5 people, including the CTO.
