I applied online. The process took 5 weeks.

Process is very long, it consists of a 1-hour screening and 3 live-coding interviews in HackerRank. The live coding are okayish described, you can always ask some clarification questions to the person that interviews you. You have to implement an interface—so that's really nice as opposed to some algorithms live coding. The interviewers are nice and provide help.

The only thing that I dislike is the time consumption:

• 3 live-coding interviews, 1.5 hours each
• Waited in-between for 3-4 days to get the interview result

That's a really long process.

1. Implement some interface - was about applying correct data structures.
2. Implement some interface - was about applying async/await and parallel principles.
3. How does async/await work?
4. Explain why you used this built-in structure?
