Absolutely unprofessional. The interviewer reused a meeting invite. This meant that when I joined a minute early to sort out my camera and microphone, I interrupted a previous candidate. The meeting was touted to be 'a chat to discuss the opportunity', but a technical screen was sprung upon me by the HR person. The interview concluded with the interviewer telling me that they could pass me on to the next stage, but that I should be brushing up on my Java if I want to pass. This is an interview for a job ad that claims, "Most of our code is in Java, but we're pragmatic - we'll use whatever makes the most sense to complete a task (previous experience with other languages is great!)" It seems that Canva is looking for a very specific kind of engineer, which is fair enough. I'm not that engineer, which is fair enough too.
