It had 3 rounds of interviews (including the initial call) - first one with a recruiter colleague (initial call) -> this was a general discussion about the company and about my preferences and expectations - second with the recruiter colleague and a person working at the company -> this was a bit more technical one about my experiences, and I got more information about the company culture - third a technical one with multiple coworkers -> this was a mainly theoretical questions about the future technologies. There was an option to bring some code samples too (which I did)
