02 / Hiring process
Three stages, and one of them decides it
3 stages from application to offer. CodeSignal technical assessment is reported to be the one that decides it.
3stages
01
Recruiter phone screen background, motivation, and logistical fit
Reported to run 15 to 30 minutes, covering background, motivation, and logistical fit before any technical evaluation begins.
02
CodeSignal technical assessment an automated coding assessment used as a top-of-funnel filter
Reported to be a self-directed, timed CodeSignal assessment covering data structures and algorithms, used explicitly as a top-of-funnel filter before any live technical conversation. Sales and other go-to-market roles are reported to skip this stage in favor of a live discovery-call exercise instead.
03
Final round panel live debugging, system design, and a real behavioral round
Reported to run as a multi-session panel of two to three interviews, with engineering candidates describing live pair work fixing genuinely broken code alongside an interviewer rather than a standalone algorithm problem, plus a system design conversation and a values-based behavioral round.
Ask before the interview: what will this round cover, who will I meet, and is there anything I should prepare?The question almost nobody asks
03 / Question library
Interview question practice library
The CodeSignal assessment, the final panel, and the eight named values apply broadly across departments, so the core set below covers that ground. Each department then adds the depth specific to it.

01 Klaviyo works exclusively with B2C brands trying to own their own customer relationships. What draws you to that specific angle, not marketing software in general? Motivation Open guide

05 / The eight values
What is actually being scored
Klaviyo publishes eight core values in this exact language on its own careers site, each with a fuller description behind it. Bring one real story for a few of these rather than a general answer about moving fast.
8stories
Put customers first
A time you prioritized what was best for the customer over what was easiest for you or your team.
Win together
A time you disagreed with a teammate directly, then committed fully once a decision was made.
Know the score
A time you used data and past performance, not just effort, to judge whether something had actually succeeded.
Be meticulous in your craft
A time your own rigor and preparation is what made a piece of work good enough for people to rave about.
Move fast, no shortcuts
A time you moved fast on a deadline without skipping a step that actually mattered.
Drivers wanted
A time you took ownership of a problem that wasn't formally yours to fix.
Stay hungry, stay humble
A time you took a calculated risk, got it wrong, and said so plainly.
We're 1% done
A time you kept pushing on something already considered a success, because you saw more room to improve.
06 / Before you apply
Where candidates lose it
Pro
Where candidates lose this before anyone meets them
The part of the process that eliminates most people is not the interview. It is what happens around it, and almost none of it is written down anywhere.
- The assessment answers that read as dishonest rather than confident
- What the availability question is really deciding
- The application detail that cannot be edited once submitted
