First contact was from a recruiter on LinkedIn after which I was connected with a different recruiter, who I liaised with through the hiring process.
First step was a general chat with the recruiter, then a deeper dive conversation about my skills with the hiring manager, followed by a Codility test that focussed on DevOps stack technologies.
The whole process was very well organized and every one I dealt with was really friendly. It seems like an awesome company to work for.
