I applied online. I interviewed at Datacom Systems in Jun 2026
Interview
The first interview is called "Discovery Day", it goes for about 45 minutes and they tell you a bit about the company and you get an opportunity to talk about yourself and your background. They then ask you about your transferrable skills, what youve been studying etc. Make sure you complete their modules to have the best chance, they are hidden in the interview booking email. None of us saw them and the interviewer seemed pretty disappointed. They then make you do a test which involves a cognitive test (surprisingly really difficult), a typing test and a basic IT knowledge test (very easy).

Interview
The process consisted of three interviews: an initial screening, a technical interview, and a final interview with the team.
The initial interview focused on confirming your skills and experience. After that, you’re asked to prepare an architectural diagram of a system you’ve built or contributed to - something like a simple flowchart is sufficient. The technical interview centers around this diagram, with interviewers diving deep into different components. They clearly have strong expertise, so expect detailed questions. Topics included cloud technologies, AKS, system design, CI/CD, and general DevOps concepts. They won't ask questions that are clearly outside of the list of skills they posted in the job post or unrelated to the system you presented.
The final interview was more of a casual introduction to the team.
Overall, all interviews were conducted in a relaxed manner. The technical portion is challenging, but manageable if you have a solid understanding of the system you’re presenting - which you should, since it’s based on your own experience.
