Exciting startup positioned perfectly to leverage enormous breakthroughs in medicine - Anonymous employee Personalis Employee Review

I really enjoyed my work and the team was very helpful!

None that I can think of

This is a very exciting mission to be a part of, and 2025 was definitely a year that saw some great developments for this company's reputation and growth. This is a company where most every role will allow you to grow and contribute immensely. Almost everybody seems to become an expert in something that makes them a respected and important part of the team. I have felt very advocated for by my managers and team, since the beginning of the hiring process. They very much want to see me succeed I feel. The office's amenities are quite nice for being a small company, and there's still fairly good flexibility for hybrid work on most teams.

It's a 24/7 operation, so I and many others will have to think about work even on off days. It's not a strict expectation, but responding to emails or checking messages will often happen outside of the typical 9-5. That all said, I have not felt like my own work/life balance is miserable (I cannot say the same for everyone, though). It takes quite a while to hit a stride of really knowing the ins and outs here. So much knowledge on how to do things is just in peoples' heads, and the experts are frequently too busy to really sit down and walk you through it as you onboard. Learning can take quite a while, and may be overwhelming at first. There are some people who have clearly taken on or been assigned too much responsibility for one person to reasonably maintain, which just doesn't feel fair to them. And it puts pressure on those folks to never really take true time off.
