First, submit cv and CUSTOMIZED cover letter. This basically determines if you get a call back. Then the telephone screening stage. Then on-site, then culture fit interview. Process went smoothly, with engineer. They were very friendly and helpful.

3 interviews. First one was a telescreen with a short chat, and some live coding exercises - took around 30 minutes. Second was around 2 hours(?) which was a technical exam, starting with writing a console application (you're told what it needs to do) whilst explaining your reasoning, whilst you're doing this a few engineers watch and ask questions. This was then followed by a code reading exercise. Third was a culture fit interview, which was just answering questions regarding work ethos and team work etc.
