Process
I had a general CodeSignal assessment, followed by a Karat interview.
This interview involved a DFS-style programming question with a matrix, which I did not perform well on, and I haven't moved forward since.
Questions
For the Karat interview, there were three Big-O analysis questions, followed by a coding assessment, which was very long and confusing.

Amazing culture. Hopefully that stays
Software Engineer • Current Employee
March 20, 2026
Pros: - Great culture and emphasis on collaboration and having fun.
- Made several lifelong friends here.
- Post-IPO stock gains were great while they lasted.
- The CEO is smart and still in 'founder mode'.
- It's fun to work on problems in education for a brand that people love.
Cons: - Compensation is 80% of what you would get at Google or Facebook. The company is relying on its feel-good mission and stock growth to make up for the remaining 20%. The recent stock price crash has made this worse. HR had better act soon before the best talent leaves.
- We're hiring more people, but the scope of work for each person seems to be getting smaller over time.
- Pittsburgh is a great city to live in, but it limits your career opportunities if you want to switch companies.
