Pros

Human Resources department has been doing a great job at posting fake 5-star reviews on Glassdoor, all to convince the founding partners and the outside world that everything is just peachy.

Cons

Compensation is low compared to peers. There are no real growth opportunities. If you want to learn something new, then forget about this place and move on. The technology is arcane, bloated, poorly managed, and plain old. You will be told lies at the interview about the so-called state-of-the-art internal technology stack. There's no real innovation either, only pretend business-unrelated ideas which never fully materialize. Many promising projects silently fail. Most VPs and MDs are pretty bad at their job, although they are very good at blaming each other for failures, taking credit for each other's accidental achievements, exaggerating their own results, and convincing the upper management that they're worth the unreasonably high compensation. Partners have no idea what's going on and why things aren't working anymore, but they keep on introducing and removing dubious workflow/HR procedures, restructuring the company every 6 months, moving people around, reassigning responsibilities, and hiring external CTOs. Don't waste your time there!

Pros

Strong learning environment for new grads, with exposure to smart colleagues, interesting research problems, good tooling, and generally strong compensation and benefits. The culture encourages rigor, careful thinking, and collaboration across research and engineering.

Cons

The learning curve can be steep, and it may take time to understand the codebase, research process, and expectations. Feedback and project direction can sometimes feel ambiguous depending on the team or manager.
