Pros
Competitive pay, some good people, stock options
Cons
When I started, it was under the guise of a patient-driven mission with dedicated employees who all seemed to work well together but that positive experience was limited. Guardant works its employees hard to bring in more money for the company at the cost of a work-life balance. Management has no management experience or training and are only promoted due to blatant favoritism. Guardant is quick to fire its employees, without notice or the opportunity to correct actions and improve, leaving everyone terrified for their jobs. The result is a toxic work culture where everyone is afraid to be perceived as not doing the perfect job, so many employees and managers will throw others under the bus to avoid the scrutiny of their work performance and avoid being targeted. It is as if getting someone fired is a badge of honor there. When the test isn't selling as well as management feel like it should, there's usually another round of people being let go without solid grounds for dismissal. Most of the managers were some of the least professional I have ever worked with. I often heard of my job performance from other people and management was incapable of assuming positive intent for actions taken. Most people stayed because the company went public but now they're losing a lot of very talented people due to the poor work culture they created. In my time there, a type of "mean girl" culture evolved that developed the systematic targeting of individuals in the department based on favoritism until they were forced to quit or were fired (four in the course of a year).
