The first recruiter gave me a case study, which required me to learn Salesforce. I spent over 60h on it and presented it to two managers. The managers shut off their camera and mic, so I had no possibility to see their reactions. They interrupted me during the presentation and asked some questions, which were clearly asked to see how I could cope under pressure. They promised to get back to me, which they never did. I sent an email to ask how the process is going, which has not been answered. Very unprofessional. I also had to hold off any other recruiting processes so now I am standing without any options. Very unprofessional recruiters!
