Submitted resume through Linkedin and received an email to schedule an interview. Right after the finished of the interview, received an email as a takehome assignment asking applicant to create a presentation within 5 hours. After sending back the presentation on time, got ghosted for a month. They then sent out a rejection email where they cc'd all the other applicants who didn't pass. Very unprofessional to reveal applicants’ personal information and not to mention the fact that they ghosted applicants for a month without even replying the receiving of the assignment.
