      Average interview

      Application

      I interviewed at Klaviyo

      Interview

      Highly unprofessional throughout the interview process. Does not understand if you need to reschedule for personal reasons and if you are in a different time zone. Do not recommend it if you are looking to move into a friendly place to work.

      Question 1

      Questions on experience but did not bother to ask about my expectations from the role

      Application

      I applied online. The process took 4 weeks. I interviewed at Klaviyo (Boston, MA)

      Interview

      1 HR interview, 4 technical interviews. Everyone was very pleasant and nice. Team manager seemed really nice, seems like they are working on interesting problems. The role was specifically for an LLM and NLP role. It seems like they are doing pretty well overall.

      Anonymous interview candidate
      Boston, MA
      No offer
      Negative experience
      Easy interview

      Application

      I applied through a recruiter. The process took 1 day. I interviewed at Klaviyo (Boston, MA) in Dec 2023

      Interview

      Low-quality interviewers just take interviews for time pass. If they feel you are more than good they will reject you. The person who took my interview never bothered to introduce himself what the company is doing what kind of projects they are working on, and what positions they are trying to hire. He started with a dice question and thought I would struggle to solve it for some time, but I was able to solve the problem quickly and able to answer with precision then the Python question with simulation on the dice and he was expecting I'll take a long time to solve, but the moment he asked me the question I knew how to solve the problem and I explained him as I started to code and was able to solve much quicker with 15mins to spare for some reason he felt offended. I tried to ask questions about the role and the company's work culture but he declined to answer any and closed the call abruptly even though I wanted to learn more about the company.

      Interview questions [2]

      Question 1

      Dice A with four 9's and two 0's Dice B with four 3's and two 11's If you are allowed first to choose the dice which dice you will choose so that the probability of you winning in the first roll
      1 Answer

      For the above question generate the simulation where the simulation will play 1000 times and then get the probability of the Dice A winning out of 1000 simulations.
