I applied online. The process took 5 days. I interviewed at Levi9 (Novi Sad) in Sept 2016
Interview
First you answer technical questions test, recommended time one hour, basic knowledge of java, mysql and web protocols. After that you talk with HR in details about your CV, background and requirements for position they offer. If you pass the test they invite you on technical interview with programmer, if not, they send you a feedback e-mail with details about what you should improve. I want to note that conversation with HR is very pleasant, i didn't felt so comfortable in any other job interview. Also, half of conversation is in english.
