      Software Engineer Interview

      Jul 3, 2020
      Anonymous Interview Candidate
      Chicago, IL
      No offer
      Negative experience
      Easy interview

      Application

      I applied online. The process took 4 weeks. I interviewed at Cloudflare (Chicago, IL) in Mar 2020

      Interview

      Absolutely AVOID. So many red flags during the interview. Process: 1. Call with hiring manager 2. Take home coding challenge 3. 4+ hours of interviews 4. ??? I revoked my application after round 3. Experience: The call with the hiring manager was weird. It was easy to tell he didn't want to be there and kept stressing that they really wanted to hire someone in Lisbon Portugal despite the job being posted for a US location.... I told them no, I will not relocate to Portugal from the US. The coding challenge was a breeze. After I turned it in though, the hiring manager contacted me again asking if I was sure I wasn't willing to relocate to Portugal. Again I told him no. Moved on to the in person (virtual interviews) To sum the virtual interviews up: none of the interviewers were prepared, stumbled over their own questions and didn't really seem to know what they were asking. On top of that a few of them were extremely rude. Rolling their eyes picking up their phone and texting, scoffing at some of my valid answers. The best part was when one guy rolled his eyes and threw his head back and looked at the ceiling for 5 minutes while I spoke. The cherry though was when I asked the question: What would you do to make a new team member feel welcome and fit in? His answer: "that sort of stuff doesn't apply to you, we are a close nit team but since you're not going to be at the same location, I don't care about who you are". After this interview, I revoked my application. (They still contacted me twice to let me know I was no longer being considered - thanks I know) This is not a good place to work if these are the people they have interviewing. AVOID cloudflare at all costs.

      Software Engineer Interview

      Apr 8, 2026
      Anonymous Interview Candidate
      Austin, TX
      Declined offer
      Positive experience
      Difficult interview

      Application

      I applied online. I interviewed at Cloudflare (Austin, TX) in Mar 2026

      Interview

      Started with a 30-minute conversation with the hiring manager. He was amazing, very friendly, and the questions were mostly resume-based. The next round was a 1-hr TPS interview with an engineering manager. It was a HackerRank-style question (not typical LeetCode), but practicing LeetCode definitely helped in choosing the right data structures. After that, I had a conversation with the recruiter to discuss salary, location, next steps, etc. The interview loop consisted of 5 rounds: 30 mins: Culture fit (behavioral questions), 45 mins: PM interview (behavioral, focused on collaboration with PMs), 45 mins: Debugging round (debugging a working system - fairly easy), 1 hour: System design (medium to hard), 45 mins: AI-assisted coding round Overall, all the interviewers were great to interact with and very supportive throughout the process. The AI-assisted round was similar to debugging, but they expected me to “vibe-code” using AI to identify issues and fix bugs or add features. After clearing these rounds, the final steps included an office visit and a 15-minute call with a CXO.

      Interview questions [1]
