In many online technical assessments, you’ll typically encounter two major segments.

First, you’ll face coding challenges—often two problem-solving tasks that test your algorithmic thinking and familiarity with data structures.

Then comes a workday simulation, where you respond to a series of emails as though you’re at work, tackling tasks, providing solutions, and prioritizing requests. This simulation checks your communication skills, time management, and teamwork approach by having you explain technical decisions, outline steps to resolve issues, and address multiple concurrent tasks—just like in a real-world environment.

We’ve received multiple customer complaints about slow response times in the new feature we rolled out last week.

Could you walk us through your approach for diagnosing performance bottlenecks in our service and propose how we could optimize it for faster throughput?

Please include any metrics or tools you’d use, and provide an estimated timeline for resolution.
