I first saw the add on Stackoverflow but the hiring process went on Smartrecruiters.com. i received an email to schedule an interview, during the interview i spoke about myself and got some easy technical questions they were easy the hr was wonderful and it took us about 15 minutes. In the second round it was a meeting with two senior devs it was about an hour. I have been asked some questions about the php language, git and oop. I also have been asked some math question. I messed it up in some questions so i didn't make it to the next step. Over all the process went smoothly and it was a pleasant experience, they're very professional.

Phone interview but there was not much technical issues. Also asked SOLID principles for junior developer. They asked for some general question and very low quality technical questions. Also this was a fresh level job but they asked about design pattern. They never gave any problem to solve.
