      Senior Software Engineer Interview

      18 Apr 2019
      Anonymous interview candidate
      Boston, MA
      No offer
      Negative experience
      Average interview

      Application

      I applied online. The process took 2 weeks. I interviewed at Klaviyo (Boston, MA) in Apr 2019

      Interview

      First a short phone call with a recruiter, followed by a 30 min phone call with a software manager. They then asked me to come onsite for a 1 hr coding test/review. After that, there was a coding challenge for building a full stack web application (they prefer you using Python and Django). If this goes well, there will be another onsite interview of 5-6 hrs. I got rejected due to some imperfections in the coding challenge. According to the engineer who reviewed my code, I don't know how to handle errors and exceptions, even if I have try...except block in every piece of my code. The recruiter gave me a short tour on my first onsite. It is obvious that their employees are predominantly white (read the posts on Benefits page). I am a person with color, and I suggest you avoiding this company if you are so as well.

      I applied online. The process took 1 week. I interviewed at Klaviyo in Jul 2025

      Interview

      Typical interview process. Recruiter call, online assessment, and then supposed to have a hiring manager round. I cleared the online assessment but was ghosted after that round. No response from recruiter.

      Easy interview

      Application

      I applied through a recruiter. The process took 2 weeks. I interviewed at Klaviyo

      Interview

      The recruiter reached out via linkedin, then set me up for an OA which I aced, and then arranged a 45 mins conversation with the hiring manager. After this they ghosted me. Totally unprofessional.

      Interview

      Round 1: Coding Assignment (CodeSignal) A take-home or timed industrial coding challenge from code signal Round 2: Hiring Manager Interview A conversation with the hiring manager to discuss your background, interests, and alignment with the role. Onsite Rounds: Round 3: Deep Dive – Work & System Design Discussion A technical deep dive into your past projects and contributions. Be mindful of not just the architecture, but also why some decisions were made. Round 4: Leadership & Behavioral Round A structured behavioral interview to assess leadership, teamwork, and problem-solving in complex situations. Focuses on past experiences, conflict resolution, and decision-making skills. Round 5: API Design & Best Practices (Coding Round) A practical coding session, not purely algorithmic but focused on designing and building a small API/system from scratch. Asked about scalability, maintainability, and software design principles. Round 6: System Design Enhancements Given an existing system design, you’ll be asked to analyze it and propose improvements. Expect discussions around scalability, reliability, trade-offs, and edge cases. I guess I failed at this step, since it was an unknown with this style of interview. Great people involved and were very accommodating.
