I applied online. The process took 4 weeks. I interviewed at FIS (Belgrade, Central Serbia)
Interview
The process consists of 4 stages, the first is CV screening, then there is an online test on HackerRank. If they are interested, they will call you in 2 weeks, followed by a technical interview lasting 45 minutes. If they like you, they can contact you after 48 hours to two weeks, followed by the HR final interview, which is there to bring the candidate closer to the conditions and principles of the company's work.
