Perficient ECommerce Project Manager interview questions

Initial call with recruiting was quick and easy. First interview with a PM was 3 weeks later, due to holiday/summer/scheduling. Second interview was a required presentation to a team, which was "new" to them which went well. They needed some feedback on the process and gave them my impression - too little information for what they asked. Then I was Ghosted. No communication from them, little response to emails, waiting for budget from projects excuses. I hope they don't treat their clients this way.
