due to covid it was supposed to be by phone but when we planned a time and date for the interview, the person interviewing me did not call and i had tried to contact her but got no reply. so unprofessional

There were two processes in the interview. The first one involved using a tablet, and playing some games that are installed, there were also some pattern recognition with numbers that were involved (honestly, I don't think they cared about this, just seems like they added it to make it look like you're applying to an official software company) and another just basic questions on data structures and algorithms, and other software generalities.
