Senior Full Stack Developer Interview Experience - Waterloo, Ontario
Process
Applied online, had a phone screen with a recruiter, then a technical interview via CoderPad. Received a comprehensive prep guide focusing on graphs, topological sort (12 pages on Alien Dictionary), and basic data structures including "Arrays (understand when it should be used)."
The actual technical interview tested interval scheduling with sweep line algorithms - an advanced algorithmic pattern not mentioned anywhere in the 18-page prep document. This is not basic array usage; it's a specialized algorithm requiring specific preparation.
When I struggled with the unfamiliar pattern, hints were provided, but explanations were unclear. With 5 minutes remaining, the interviewer asked if I had questions rather than allowing time to complete the solution.
Received rejection shortly after. The disconnect between prep materials and actual testing made it impossible to demonstrate my capabilities effectively.

Faire Work Experiences
- 2.0High-pressure culture without high-pressure rewardsEngineer • Current EmployeeWaterloo, Ontario, CanadaNovember 2, 2025Pros: Get to work with cool tech, and there are some great people here.Cons: The comp team doesn’t understand Canada and market norms. It’s this constant pressure to raise the bar for average pay. I believe this is worse outside of engineering too. There’s no RRSP matching, even though the recruiter promised it was coming during my recruitment process. There are no bonuses. The company outsources lots of functions to save costs – doesn’t really scream “cares about local communities” to me. Hiring and promotions are slow due to zero headcount growth over the last three years.
