Pros

* Catered lunch on two of the three mandatory in-office days—if you consider that a perk rather than just a consolation prize for the commute. * A professional development stipend now exists, even if it’s less generous than the benefits it replaced. * Corporate Libby account, for when you want the company to feel like it’s generously gifting you the same thing your local library offers for free. * Great place if you enjoy completing essays disguised as self-reviews.

Cons

* The forced Return-to-Office policy is now three days a week, up from two, creating logistical nightmares for both in-office and remote employees. Hope you like traffic and canceled childcare arrangements! * Once-envied perks, like unlimited vacation outside the U.S. and reimbursement for personal development, are gone. You can still read books or upskill, but only if it aligns with *company-approved* professional goals, and while it hasn't officially happened yet, it’s only a matter of time before the U.S. "unlimited vacation" policy is redefined to "unlimited requests for time off, subject to approval." * Internet and wellness stipends slashed—because apparently working from home doesn’t involve actual costs. * Removal of Slack titles to "protect higher-ups" is a fascinating exercise in transparency. Definitely not dystopian. * "Pulse" surveys are semi-anonymous and semi-useful. Management sees them as more of a ritual than a tool for actual change. * A growing divide between remote and in-office workers: the former are treated like second-class citizens, while the latter anxiously wait to see if their in-office days will increase at a moment’s notice. * A cumbersome self-review process that focuses more on company-defined "impact" than personal goals. You’ll spend days crafting answers just to be graded on a rigid 6-point scale that’s designed to make nearly everyone feel mediocre. * Legacy systems create a chaotic workday. A single deployment can derail hours of work, and issues caused by other teams will become your problem faster than you can say “monolith.” * Office overcrowding solved not by loosening RTO policies, but by evicting employees from their desks and instituting a hot-desking system—with a cheerful CEO assuring us this is "progress." * Recruiters aren't dishonest but aren't clairvoyant either. The role you're hired for might change drastically between the offer letter and your start date. * No staging or QA environment, which means every deployment is a roll of the dice. One wrong move, and it’s straight to the production servers—where, naturally, everything goes perfectly... until it doesn’t.

Pros

Benefits, free food, tech talks.

Cons

I had high expectations coming into Klaviyo, but the reality fell far short. The biggest issue is leadership. There is a clear lack of the experience and judgment needed to effectively lead a modern engineering organization. Decision-making often feels reactive rather than strategic, and there’s little evidence of long-term technical vision. Instead of empowering experienced professionals, leadership tends to micromanage as if they’re overseeing a group of junior interns rather than seasoned engineers. From a technical standpoint, the quality of the codebase and product is concerning. Much of the system feels like a patchwork of rushed solutions—often reminiscent of a half-baked college project rather than a mature, production-grade platform. Core areas suffer from poor system design, weak data models, and significant technical debt that is consistently ignored rather than addressed. Project expectations are frequently unrealistic. Leadership pushes aggressive timelines without accounting for the underlying technical challenges or existing debt. There’s little regard for sustainable development practices, which leads to constant firefighting instead of building robust, scalable systems. The result is a frustrating environment where engineers spend more time working around problems than solving them properly. For a company at this stage, the gap between where things are and where they should be is hard to overlook.
