Viber Interview Guide
Everything we know about interviewing at Viber: the process stage by stage and what each round tests.
Interviewing at Viber
What the process looks like, and what Viber is really testing for.
You go through a mix of HR screening and technical interviews, and the technical side is the centerpiece. Reports explicitly mention technical interviews with team members for technical skills and problem-solving, plus deeper discussion that can include DevOps practices and problem-solving.
What they test is strongly weighted toward engineering fundamentals plus their data and advertising domain. Across the extracted topics, Linux, QA Engineering, Mobile Engineering (general), Algorithms (Data Structures & Algorithms), Data Science concepts, and contextual advertising efficiency appear at the very top (percentile 100), with Data Structures, Contextual Targeting concepts, and AWK also very prominent.
Based on candidate reports, the loop includes several screening and interview steps, including initial screening by HR, at least one additional HR wrap-up interview, and technical interviews. However, there is no reported offer rate in the data you were given, so you cannot rely on these reports to predict whether you will get an offer.
Your interview topics are unusually concentrated in Linux, QA, mobile engineering, and contextual advertising and measurement, with algorithms and data structures also heavily represented. If you prepare only generic backend or generic ML, you are likely to miss the domain-specific emphasis shown in the topic distribution.
