Real, anonymous reports from people who interviewed for Software Engineer at Klaviyo, newest first and distilled into what to expect across the loop.
After an initial recruiter call, I got pushed into assessments pretty quickly and then into a hiring manager conversation. The assessment was done through CodeSignal and it was more practical than classic leetcode-style problems. I remember it unlocking through multiple steps, and while I didn’t finish every stage, I still made it far enough to get to the next round. My hiring manager interview mixed a project deep-dive with behavioral prompts, including the usual “tell me about a time” style questions.
My early stages moved quickly and followed a pretty standard pattern: I started with an easy recruiter screen, then I got an online CodeSignal assessment. In the recruiter call, we kept it straightforward and role-focused, and I also ended up discussing how I used AI day to day and how I balanced design work versus coding.
The interview process typically begins with a recruiter call focused on behavioral questions and role fit, followed by a quick transition to a technical assessment. Candidates noted that the recruiter was generally helpful, but experiences varied from organized to chaotic.
Candidates undergo an online assessment via CodeSignal, which emphasizes practical coding skills over traditional algorithmic problems. The assessment is structured in multiple stages, where performance in earlier sections determines progression to later rounds.
The technical interviews often include collaborative coding sessions where candidates fix existing code or enhance functionality, rather than solving standalone problems. Interviewers focus on real-world engineering scenarios, including debugging and API design.
Behavioral interviews are integrated throughout the process, assessing candidates' past experiences and cultural fit within the company. Questions often follow a 'tell me about a time' format to gauge situational responses.
Candidates reported varying levels of organization and communication throughout the interview process, with some experiencing clear timelines and others facing delays and lack of follow-through. The overall structure can feel intensive, with multiple rounds packed into a short timeframe.
While many candidates found the interview experience positive and respectful, some expressed frustration over the lack of constructive feedback after interviews. The process can be exhausting due to the number of rounds and the intensity of the evaluations.
