I applied online. The process took 3 weeks. I interviewed at Klaviyo (Boston, MA) in Nov 2021
Interview
As is standard with the hiring process for technical positions, there were a series of technical and cultural interview sessions that intermixed over the course of a couple weeks timespan.
The technical portions were challenging, but actually focused on "real-world" situations/problems and therefore allowed actual productive discussion and collaboration to occur during the interview sessions. I have to say that the process was quite enjoyable.
Thank you so much for taking the time to share your feedback! We're so glad to hear that you had a positive interview experience, and hope you're enjoying your time as a Klaviyo!

HR screening. Asked me some questions about software basics and sent me a code signal link. Asked about how I utilized AI in day to day work and how much design work versus coding task
ICF Codesignal, recruiter screen, and then final interview. Codesignal was easy as long as you prepped for it, there are many examples of ICFs online. Recruiter screen was normal. Final interview was not DSA related. Mostly related to the real experience of being a swe.
I applied online. I interviewed at Klaviyo (London, England) in Mar 2026
Interview
The interview process was generally well structured. I had an initial 30-minute recruiter call, followed by an assessment task and a hiring manager interview. The final stage consisted of three separate one-hour interviews covering different skill areas, with two interviewers in each session. One focused on frontend skills, while the others leaned more toward backend and broader technical competencies. Overall, the experience was positive, though having a three-hour final stage in a single day felt quite intensive.
