Pros

You’re helping people find answers/information to their health issues.

Cons

-unlimited PTO is a lie. Managers can require for you to write up multiple explanations as to why you should be granted PTO and have to get approvals from multiple people, including HR. Takes months before a PTO request is given a final decision. There seem to be “rules” for how many days you can take, but you won’t be told what they are, and it’s frustrating to navigate. Also, PTO was randomly and suddenly capped by management right before the holidays (this was right before Thanksgiving/Christmas holidays, and many people could not take time off that they were planning on). - deadlines are incredibly tight and often shortened multiple times on top of that, leading to constant burn-out, as you don’t get a slower-paced window of time to recover a bit from the last deadline rush. - I only know one person on my team who has decent work-life balance, and it was the most junior person on the team whose work is not as demanding. Most everyone else worked long hours and weekends to keep up. This issue would be cautiously shared between coworkers but no-one dared to bring up to management because then the person who brings that up is blamed for not being efficient enough. We were also constantly encouraged to “work in parallel”, meaning instead of waiting for people to finish their parts before passing it on to the next person, we had to do multiple layers of a project at the same time, causing a LOT of issues and re-work when the first part had mistakes or had to be re-done, leading to people drafting later stages of a project to also have to constantly re-do their work. This was incredibly inefficient and frustrating. Management knows that the deadlines are tight but if anyone hinted at it, the response would be “well, this is Tempus.” Management has also joked about the pace of Tempus by saying things like “yeah, that’s SO Tempus (laugh).” - as others have mentioned, no 401k match (this is brought up almost every time the CEO has a quarterly or semi-annual Q&A, but still no change), no bonuses, no raises, no promotions. Our management told us that we can’t even be considered for promotions or raises for at least 2 years from when you are hired. - the culture is fast paced and still has a “start-up” vibe. As others have noted, management and leaders are not properly trained or experienced. You’ll see senior managers who look like they are still in college (compared to larger companies where titles like that are harder to earn). Cursing is normalized on some teams- I was shocked at the lack of professionalism when I first joined Tempus. Overall, if you don’t have major responsibilities, like children, or any personal crisis/major difficulties that you’re navigating in your off time, and can work long hours, this place will teach you a lot and can be a great learning and growth experience. Otherwise, if you are looking for work-life balance and good benefits, stay clear, or at least don’t plan on staying here long.

Pros

Unlimited PTO (although it's not truly unlimited. Leadership internally caps people out at 10 days max and flags others who goes above), free snacks and coffee, young culture

Cons

No 401k matching, leadership is not consistent with their stories, they say they are for you but are entirely against the greater team, deceptive and toxic work culture, most managers are first time managers and not properly trained, little growth, very political on my team -- needs to be part of the social club to be liked. Would not recommend this company or the science teams to anyone. Also, the company is greedy and does not care about genuine science, heads up to future clients--they just want to sell you data with the data being messy and incomplete. They do not care about generating meaningful data and science.

Pros

Lucky if you are in a good team. Good learning opportunity.

Cons

Horrible, horrible compensation. Management is all talks and no show. They keep adding new resources but don't value the existing employees.
