I applied online. The process took 6 weeks.

I took part in several stages: 1. get-to-know interview with HR 2. technical screening with engineering lead 3. programming homework to do (up to 10h of workload) 4. solution analysis and talking around the problem with an engineer 5. another technical interview which included algorithmic live coding and distributed systems problem analysis and discussion After doing all of that, the company went silent for over a week.

During that time I tried reaching them several times as I wanted to get at least approximate date of the results. Finally, I got a message with simple rejection without any real feedback. After all the effort, I expected at least some comment.

Although I learned some stuff and it was a challenging process, the concluding step left something to be desired and shed a negative light on the company.

One of the questions from the initial screening was:

What is the complexity of quick-sort?
