Great Benefits, But Culture and Leadership Fall Short

Pros

Unlimited PTO, excellent and nearly unmatched benefits, guaranteed three day weekend, every month, causal office—not overly stiff or corporate.

Cons

Unorganized!! The rigid in-office policy feels outdated. Hybrid work is the standard at most forward-thinking companies, yet Arcellx continues to require on-site attendance. Multiple employees—including some C-suite leaders—have expressed frustration, but say little because the CEO lives nearby and seems to assume everyone else does too. While the office is well-stocked with snacks, if we’re expected to be in person, a lunch service or some kind of meaningful incentive would make a difference. Compared to other tech companies offering hybrid flexibility and real on-site perks like meals, Arcellx is falling behind. Favoritism is a real issue. The commercial team is given little to no flexibility to work from home but then again that is certain individuals get to work from home, some teams operates almost fully remotely—and continues to receive promotions (a whole team was just promoted) which is a indicator that you can still get your job done and be great WFH. The CEO rarely visits the Maryland office but invested heavily in office decor, only to mandate in-person work. A large number of employees consistently express dissatisfaction with this. Lastly, as time goes on, I continue to hear and see more employee dissatisfaction, work gossip, which is likely to lead to higher turnover.

No advancement or career growth

Pros

Great benefits especially the 401K plan

Cons

Lack of advancement and career growth. Promotions are instituted not merit based. Your employees help you to get to where you are today. Only promoting leaders as if they did the work leads to dissatisfaction . The negative reviews on here are true.

Thank you for sharing your thoughts, and your concern about who receives promotions. We work hard to ensure that our benefits and rewards are comprehensive, and that all individuals can advance based on exceptional contributions, merit, and values. In the past three years, 45 people have been promoted (on an average headcount of 145) and 95% of those promotions were for people below the VP level. We also implemented a recognition tool that has significantly increased companywide recognition. If you’d like to discuss your ideas with a member of the leadership team, please reach out to any one of us.
