I applied online. I interviewed at Klaviyo (Boston, MA) in Nov 2020
Interview
First round was behavioral and slight technical. It was more like a HR round. Second round was about solving and fixing codes, mainly about REST APIs, Python and SQL. They will share the messed up code and you have to fix it to make it more efficient. Third round was would be more technical I believe.

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.
