I applied through an employee referral. I interviewed at Klaviyo (Boston, MA)
Interview
Pretty straight forward. Was very impressed with the interview process. On-site went well and the group of people I met were very friendly. The only issue I had was with the post interview process. Received a very weirdly worded reject. On top of that when I tried to ask for feedback, my emails were ignored.
We appreciate the time you took to interview with us, and are disappointed to hear about your experience at the end of the process. Your feedback is important to us, and we've shared it with our team.

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.
