was contacted on LinkedIn by a recruiter and had a screening scheduled for the next day. During the screening, they clearly explained the role and compensation. However, I didn’t move forward in the process because they were concerned about my involvement in entrepreneurship and running my own startup

The hiring process is long, and the teamis looking deeply for a reason to not hire you ! After an HR screening (without any once of customization or real interest to your person) there is an analytics case (answers are available on Google), then there are 2 interviews with Sr Product Owners that questioned you about 1 of your experience and 1 product case. My last interviewer was always interrupting me with questions that didn't seem related to the topic (not sure if it's part of their strategy to assess the candidate). Then a last "bar raiser" interview where the interview go through each experience from your CV with the following question : who was your manager, which rating would he give you from 0 to 10, how would he describe you ... It's an intense process, very processed and guided through automated emails/reminders, that is focus on identifying your weakness rather than your strengths according to my experience. Finally, don't expect any feedback at each steps of the hiring process.
