Poor Excuse for a People Team

Pros

CLIA/PE/RD teams are comprised of extremely driven and smart employees that take initiative on improvements to lab operations and workflow. CLIA management is strong, empathetic, and listens to their employees.

Cons

The People Team has ruined BillionToOne since joining in 2021. When a team that is so far removed from lab operations oversees and dictates how the lab operates, the entire Clinical team suffers. Merit increases, promotions, wages, worked holidays, culture - the People Team unfortunately plays a negative role in all of these. CLIA team is forced to work ALL holidays. Every single one. Only certain holidays actually get holiday pay. There are no bonuses, and no guaranteed yearly merit increase to combat inflation. There is no weekend differential, though the People Team consistently denies and states it is "baked" into our rate. On many occasions, several female employees have felt uncomfortable and have had their emails and messages ignored by a particular member of the People Team. This team is also responsible for poorly rolling out a new time management system, much to the dismay of their hourly employees. Though I have worked at BillionToOne for several years now, I cannot recommend this company as long as the People Team has a chokehold on the Clinical team.

Pros

People and culture is great overall. Business is doing well. People are smart and hardworking. Free lunches, snacks, and frequent parties with food and drinks.

Cons

Most lower level jobs are poorly paid. Hiring only hardworking superstars but only a small fraction gets promotions and merit increases, no bonus no annual raises otherwise, so the base salary can becomes not competitive pretty quickly. Career growth between different departments are mismatched, some departments advance people to high levels much faster than others. CLIA and R&D have hardworking people stuck at some levels. Many people are waiting for the market to warm up to leave for other opportunities.

Pros

Solid benefits, finally started giving cost of living adjustments — though they still don’t really match actual inflation. Free snacks and lunch are legit. The real gems here are the coworkers — absolute 'superstars.' You learn so much from the team because most people are insanely hardworking and talented. Management in the lab seems to be improving, especially with more transparency lately — something we've been pushing for forever.

Cons

The favoritism is wild. CLS staff (especially certain ones) get special treatment, while CLA's often take the fall for mistakes. It’s frustrating to see some CLS taking long breaks or not pulling their weight, but still getting a free pass. Meanwhile, CLA's mess up once and are shown the door. What’s worse is the attitude from senior leadership. We've literally been told in company-wide meetings to suck it up because we “signed up” for a chaotic work environment. The CEO even said in a podcast that the extar workload burden (aka burnout) people feel is by design — like, why brag about expecting people to do 2-5x the work they would at another company for the same (or less) pay? It’s giving we don't care about work-life balance...which they do NOT! Literally, heard a senior staff member talking about this in the halls, if work-life balance is important to someone then BTO is not for them. At the end of the day, this isn’t a pro-employee company — not that many are — but to openly say they want you to grind yourself into the ground for "big impact" or leave? It’s a choice. What’s even more frustrating is that these high expectations don’t apply to everyone — some people just coast by, doing the bare minimum and agreeing with whatever leadership says. Total waste of resources.
