Five rounds of video chat sessions, covering three different fields of interest in coding, all on a basic level.

The tasks are not particularly hard. What's hard is to attend all those rounds when you have a daytime job.

Coding task: Implement a simplified version of a typical container with a performant iterator. The interviewer will specify time complexity constraints. Analyze the complexity of weaker versions.

Coding task: Implement messaging. Create sender and receiver methods using only language-level tools and locks, without any external libraries or frameworks.

Coding task: Use a library method and provide its return values within a service. Make performance improvements based on pretend bug reports. Graphically present facts about its performance.
