First-hand accounts from people who interviewed at Open Systems.
Site Reliability Engineer
The whole process has 3 rounds: first, a chat with the recruiter, then a talk with the SRE Director (the hiring manager), and finally, a three-hour all-hands interview session. This last part includes a general technical interview, an SRE-specific interview, and a teamwork interview. Honestly, the interviewers were super friendly and really knew their stuff. It felt like they genuinely wanted to collaborate, not just quiz you or show off, which was refreshing. They seem to understand that nobody knows everything, and there's always something new to learn from each other. For me, that kind of attitude is key, and OpenSystems really showed that.
- Can you explain the workings of DNS, DHCP, and TCP?
- Describe your approach to debugging a problem and the tools you'd employ.
- How are go-routines utilized?
Account Executive
I interviewed with the sales director, the sales engineering team, and a few other people. They all asked good questions, and seemed to be looking for high achievers who are willing to work hard. They also gave me plenty of time to ask my own questions. Based on my interactions, I could tell this company has a really passionate team, great leaders, and is set up for huge growth. If you're top talent and looking for a great next step, this is it.
- What would you do to make an impact and succeed when you first start in this position?
- What resources would you need to get up to speed and be successful in this role?
- How would you keep generating business?
Software Engineer
The whole process was really smooth with a great team! It started with a recruiter call and then a chat with the hiring manager. After that, I had a 2-hour technical interview. This interview began with a presentation, then we dived into technical questions about unix/networking, and finally, there was a leetcode coding part. The environment seemed really stimulating, which gave me a positive impression.
- Leetcode problems
- Questions about unix terminals
- Networking questions
SRE Engineer
First I had a recruiter call that was super chill. Then I interviewed with an SRE from the team. They told me that if I pass, the next interviews would be a hands-on session on Linux, Kubernetes, and such, followed by another interview on different SRE topics, and a final interview where they'd check how much they like me personally.
- Can you explain SLOs and SLAs and share your experience with them?
- Describe your process for deploying a service within Kubernetes.
- What's your level of familiarity with networking concepts?
