Pros

- Four 10-hour workdays weekly, plus time balancing - Very strong job security - Work-life balance is very good - Work culture is good, the people are very down-to-earth and relaxed - The work supports an important, meaningful mission

Cons

- DoE work pacing is very slow at times - Opaque promotion system that seemingly rewards less experienced new hires much more than long-term employees, with respect to time in grade

Pros

Pay is alright for the area. PTO could be worse. Time balancing is nice for salaried exempt. 4 10s is nice.

Cons

Stereotypical government. Terrible culture and everyone knows it. Mostly run by career government contractors just there to punch the clock on cost-plus contracts. Very slow and with little interest in getting work done. Policies and processes are unintuitive and/or not clearly documented. The policies around remote work aren't very logical, even for roles that could easily be 100% remote. They clearly dislike the idea of remote work, but have no choice due to facility/parking limitations. They also have a two-hour remote limit for when you have to be able to report to the medical center for drug tests. You probably won't hear about that until you've already joined, but it isn't as simple as pulling up a map and seeing that you're safely within two hours; instead, they want you to actively be taking the test within two hours, or you fail. This seems very unreasonable since it doesn't account for delays outside your control. The relocation program has a 1-year payback period. You should read that as the company thinks you'll probably want to leave soon after you join, and wants to impose a large penalty to keep you there.
