      Staff Software Engineer Interview

      14 Sept 2021
      Anonymous interview candidate
      No offer
      Neutral experience
      Difficult interview

      Application

      I applied online. The process took 5 weeks. I interviewed at Illumio in Jun 2021

      Interview

      I applied for this position and the director of engineering reached out to me. He said I didn't have enough experience for staff software engineer but would proceed with it as a junior staff software engineer. I exchanged a few emails with him and he asked about static vs dynamic typing, then we had a short call about how to handle a simple phone app. The main idea is that you needed to know that you should display some sort of waiting screen while the user waited for the API to refresh. Next was a coding interview, had to basically deal with TCP requests and work with a stack/queue, wasn't too bad Next was a system design interview which was pretty tough for a junior position. My recruiter contact told me it would be 30 mins but the interviewer thought it was 45, he sounded disappointed it only went 30 mins and that's probably part of why I didn't get it

We are actively reviewing this situation to understand where our process broke down, particularly regarding communication and the alignment of our hiring needs. Your feedback is crucial in helping us identify these gaps and implement immediate improvements to ensure that future candidates do not face similar frustrations so thank you for sharing your experience with us.

      Easy interview

      Application

      I applied through a recruiter. The process took 4 weeks. I interviewed at Illumio in Jan 2025

      Interview

      1. Recruiter Interview 2. Take home coding assessment 3. Interview with a senior engineer Assessment was easy, it took them about 2 weeks to review, which could be understandable given that the company was on holiday. According to the recruiting staff, the first interview was to discuss the assessment. However, the interviewer engineer focused on technical questions on random topics during the whole interview, leaving just a few minutes to talk about the assessment at the very end, and that's just because I mentioned it. To make matters worse, it was obvious that he hadn't even seen my code, and the questions he asked were very superficial. Although I acknowledge I didn't perform on the technical questions (as I wasn't prepared or expecting that), I don't know why the company asks for an assessment it if they don't really follow their own process, it's just a waste of time, not just for them but also for the interviewee. Overall, this was a terrible interviewing experience.

      Interview questions [1]

      Question 1

      Questions about some technologies like K8s, Redis, Cassandra. CS concepts like CAP theorem, consistent hashing, caching, rate limiting, etc.

      Application

      I applied online. The process took 2 weeks. I interviewed at Illumio (Sunnyvale, CA) in Jul 2024

      Interview

      Overall interview process was mixed and left me with a poor impression on how the company handles the candidate pool. I finished the on-site panel and was ghosted by three recruiters in the company who assured me that they "move quickly" and get feedback to the candidate within 48 hours. The interviewers themselves were courteous and gave me a good idea of the project, challenges and roadmap ahead for how the company is positioning itself. The recruiting team was sloppy in handoffs, incommunicado when it came to preparing the candidate for the on-site panel and non existent in passing back feedback after I had to spend 4 hours in the office to meet the team and commute 2 hours over there and back. Overall I wouldn't think it was worth the experience and I'm assuming they passed on me but I wouldn't know since it's been two weeks of me trying to engage with three recruiters since then.

      Question 1

      Coding question was directly lifted from leetcode (hard) System design was business specific with a focus on trying to use on-premise infrastructure (in 2024)
