CIBC Product Management Analyst interview questions

The people contacting me were nice but very unprofessional. instead of emailing me to set up a time to call, they were calling me at all hours of the day which I was not expecting and missed their calls. When I would miss their calls they would text me which I thought was strange considering they had my email. I texted back sharing my availability to call which they didn't reply to and proceeded to keep calling me including once at 7pm on a Friday. Once they finally called me at a time I was free I picked up and they set up a time to do an excel assessment. I did the assessment over a Microsoft teams and submitted to them through email. this was almost a month ago and never heard back not even rejection. I emailed to follow back and still no reply. If you are going to move someone to the next stage of the interview process I think its good practice to let them know at least that they will not be moving forward.
