Flywheel Networks interview questions

The interview process for the engineering team consisted of one short phone screen and one longer in-person interview with two current Flywheel engineers. Phone screen: mostly focused on experience, projects, noteworthy items from my resume, etc. No technical questions. Lasted maybe 20 minutes. In-person interview: The main interview covered multiple broad areas of programming but focused on algorithm design and complexity, database design/data modeling, and Ruby/Rails knowledge (Flywheel is primarily a Ruby/Rails shop). I was asked to design and implement a function to find the nth prime number, as well as come up with strategies to improve my solution's performance. The database portion focused on modeling a simple application and sketching a few SQL queries for different interviewer-provided scenarios. In addition to the technical interview, a few other non-engineering employees (including the CEO) interviewed me for personality/culture fit.

2 phone interviews and one in-person interview. This includes the hiring and operations manager.
