Phone screening, three in-person interviews at their office. Nice guys, got along well with them. The interview process was positive and straightforward. After I spent several hours interviewing at their office, I was asked to complete a skills test- using Ansible to fully automate the deployment of a basic app. I spent several days working on the test before submission. They did not respond to any attempts to contact them after I submitted the test, which I consider to be very poor and unprofessional behavior on their part.
