My phone number has been contacted through the Viber app instead for the initial interview. The initial interview already includes technical questions and thorough screening of your past experiences and verifying your skills and certificates if you are actually meeting the job requirement and to check if you are fit in the role. I've been told during the initial interview that I pass. Pointers are will be given for reviewer and to prepare on the next steps. Meeting invite is will be sent for the next phase of the interview, for technical questions and demonstrating your knowledge.
