It was suppose to be a half an hour interview which ended up being 45 mins. both of the interviews were company's managers. They started with typical HR questions and asked me what courses Im taking this term and came up with fundamental technical questions right away.

After commuting almost 2 hours and conducting a 4-hour interview, they ghosted me and didn't send me any follow-up updates even though they said they would after 2 weeks. The interview process was unprofessional and unprepared.
