Process

It was a typical online HackerRank assessment. It tested your algorithm and data structures knowledge.

One of my questions was to find all nodes involved in the shortest path between A and B. It was a weighted graph, so you could use Floyd-Warshall, Bellman-Ford, or Dijkstra's algorithm.

Interesting problems and exciting industry

Senior Software Engineer • Current Employee

San Mateo, California, United States

November 13, 2025

Pros: Lots of vertical integration, so many opportunities to solve problems at the infra layer, platform/tooling layer, and application layer. The breadth of engineering is refreshing and similar to big tech, but without as large of an engineering org in sheer numbers, so impact is readily available.

Cons: Difficulty getting clarity and alignment with leadership on product roadmap and priorities. Shifting direction can cause thrash on product teams and result in a more stressful environment.

Pros: Interesting product. Nice coworkers. Good pay.

Cons: As the company and tech stack has grown, we spend more and more time on process issues (setup tasks, tooling, broken builds, trying to understand old undocumented code, secret knowledge) and less time just building new features. Leadership reneged on its commitment to allow remote work. This shows a lack of respect, a lack of empathy, and a lack of integrity.
