Process
The first round was a phone screen with a developer, which was almost entirely behavioral. They asked some questions related to my past experience, but nothing that required much prep. I heard back early the next day, though it took almost a month to schedule the next round, which was technical.
They presented me with semi-working code revolving around REST APIs, Python, and SQL. My job was to optimize it, as there were some errors as well. Honestly, I wasn't too comfortable working with Flask, etc., so I didn't do great. The interviews (two of them) were understanding and helpful if I asked for clarifying questions.
They got back to me another week later.
All in all, I truly believe this is a great company to work for, especially since they are headed for an IPO soon. Clients seem to love the product, but the hiring process was long and drawn out. Had they gotten back to me earlier, I would have explored other opportunities—but this is just the job game. Good luck, everybody!

Klaviyo Work Experiences
- 2.0Keeps getting worseSoftware Engineer • Current EmployeeBoston, MAMay 8, 2023Pros: Colleagues are smart, capable, and helpful. Career growth is possible if you’re competent.Cons: Leadership is *awful*. The CEO can’t keep his mouth shut, and blurts out something toxic every time he talks. * Shady layoffs * Rug pull on RTO * Low compensation for engineers * Brutal on call that we don’t get over time pay for
- 2.0Poor eng designSoftware Engineer • Former EmployeeSeptember 3, 2024Pros: I am not aware of many pros.Cons: Very poor eng design, and a deployment can take tons of time.
- 1.0Leadership has lost the plotSoftware Engineer • Current EmployeeApril 23, 2023Pros: There is a lot of talent at the individual-contributor level, and many people are great to work with.Cons: Leadership only cares about IPO and has been cutting costs to juice the books while lying (poorly) about the rationale to employees. Pay increases are woefully inadequate for the effort they demand, burnout is rampant; and leadership has been told this directly and brushed it off for multiple years at this point. The company runs on a bunch of early-career folks who don't realize they are being exploited, and who leave for much better jobs once they figure it out. Leadership structure is entirely top-down: The out-of-touch CEO announces a poorly-considered policy change at an all-hands meeting, then middle management is left scrambling to sort out how that will be implemented while dealing with the fallout from employees. C-suite turnover is incredibly high, likely because the CEO is a budding megalomaniac who can't talk about much other than his vision and legacy. Recent layoffs of ~10% of the company, just after giving everyone (except VP+) an effective pay cut, have left morale in the gutter and internal initiatives effectively paralyzed. Our teams have been asked to volunteer capacity to other teams (teams that had people laid-off) because that work is more important. I'll let you sort out what that says about how effective leadership is at this company. On top of that lovely situation, the CEO has mandated that everyone return to the office... so they can sit on zoom calls anyway because half the company is permanently remote. Avoid this place at all costs - they are always hiring because attrition is immense and you'll just keep getting more work without any pay increase while leadership shuffles dollars around to get their big IPO paycheck.
