Video call with an engineer. It starts of with asking for a short introduction of yourself. After that followed a series of random questions on C++. Lots of cherry-picked questions and no real type of questions that try to gauge if your able to reason about different things just "do you know about X, Y and Z?".

After giving through answers on like 90% of the questions I got a "you don't know the STL library well enough" because I did't remember by heart the name of the function that sets the capacity on a std vector. Super weird given that I answered all his other questions on STL containers as well. I'd say don't waste your time, this interview process is unprofessional and the person that interviewed me was unprofessional as well.
