I applied through college or university. The process took 2 weeks. I interviewed at Klaviyo
Interview
Mostly technical rounds with very little leet code sequences problems. Much more practical and real world examples. Make sure you know what you are building system design wise and can talk to it
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.
