      Senior Software Engineer Interview

      2 Nov 2022
      Anonymous interview candidate
      New York, NY
      Declined offer
      Neutral experience
      Easy interview

      Application

      I applied online. I interviewed at Klaviyo (New York, NY) in Oct 2022

      Interview

      The interview process was pretty hectic. It was around 7 or 8 rounds. I personally felt that there were all repetitive questions. The hiring process should have some improvements. For me it didn’t make any sense having hiring manager interview twice. Here is the interview process. Firstly you get a call from the recruiter to take details and discuss about the job. Secondly , the first interview round is with the hiring manager around 1 hour just to discuss about your previous role in depth. Then you have a coding collaboration with two of the engineers. Here you will make changes to the given code and make more maintainable and so. Then you are scheduled with 5 rounds of interview each interview for an hour. You can also call it as a power day interview. 1) First is the leadership principle round. 2) system design round 3)Algorithm round(1 hour round but I completed it in 20 min) 4)Product manager round 5)Hiring manager round. FYI this is the same person and the same round with hiring manager which I spoke in the beginning. This particular last round did not make sense as it was all repetitive, this hiring manager round he also asked questions on system design and asked to evaluate the thoughts. He asked all the questions that we already spoke in the beginning. Overall the process could be better but I enjoyed the interview. Finally I was offered a job. But I had to decline as I accepted another offer in hand.

      Interview questions [1]

      Question 1

      I was asked more of a leadership questions and more technical. For example: tell me about a situation where…. ? The questions are followed by what, why, how, where, what you did and so on. They try to cover everything possible. Just be ready with your answers. Overall if you are good at explaining your thoughts or in explaining your previous experiences you will definitely nail the interview. Good luck

      Average interview

      Application

      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.
