The process took three months. The interview process is very unorganised. It is email only, and replies take more than one week. The entire process took more than three months, and you should be prepared to wait two to four weeks between phases.

The process consisted of the following steps:

• CV screen.
• Phone screen (30 minutes), which went through everything on your CV.
• Take-home assignment involving a concurrent web crawler.
• Phone interview, which was a review of the concurrent web crawler. The interview covered how you could improve the performance of the crawler and what the limiting factor of the current implementation was.
• On-site interview.

How could you improve the performance?
