As a Croatian national, you are an EU citizen, and your rights with regard to free movement are currently governed by the citizens' rights directive. This explicitly provides that EU (strictly, EEA) citizens can work in countries other than their own, which explicitly includes "looking for work for a reasonable amount of time". You should be fine to travel to any other EEA country for a job interview on your Croatian passport; Schengen limits do not apply to you, as they don't to a full citizen of any EEA member nation.
