In one word, unprofessionalism. The interview was based on a list of topics and technologies used in the software engineering industry, starting with basic Java topics like OOP principles, Multithreading, Exceptions, I/O and continuing with client-server arhitecture, javascript questions, JDBC, Maven, Git, Security. They let you grade (0-5) every topic, so you basically have to autoevaluate yourself. After this, they start asking you questions, to see if you lied or not. It depends a lot on what people will interview you. After all the effort and time lost, in case of a negative answer, they don't tell you anything, they will not even send you an autogenerated email, which is really disrespectfull.

Interview took place online, the questions were available to answer on a site for this types of interviews, i guess this is easier for the HRs to filter down the candidate, but this type of filtering has a lot of bias.
