Process
Phone interview with a standard algorithm question.
The interviewer was friendly and the question was not difficult if you prepare and do LeetCode questions often.
HR was slow to get back to me with the results.
Questions
This is a standard LeetCode question.

Fantastic place to work and grow as an engineer
Software Engineer • Former Employee
Pittsburgh, Pennsylvania, United States
December 28, 2022
Pros: - Generally a joy to show up to work every day.
- Excellent engineering culture. Everyone I worked with seemed to be genuinely excited to be there, solving problems and working on new things.
- Management highly values employee satisfaction and career growth. I had lots of opportunities to learn new skills and take on new challenges.
Cons: - Living in Pittsburgh isn't for everyone, and most positions are located there.
- The company has grown a lot over the last few years, which has made for constant change in teams, people, processes, features, code/architecture – just about everything.
This isn't really a con for the right type of person, and it may mellow out as the company transitions out of the late-stage startup phase, but be prepared for a very dynamic environment.
