Process Street Customer Success Manager interview questions

received an email saying we’d like to speak with me and to set up a time through their links they sent. Spoke for 30 minutes, 10 minutes more than the allotted time. Felt good, the interviewer was going through the challenges they had as a growing business and who I would meet with next. Sounded like i was through to the next round. Finished the call, sent my thank you and within 30 minutes I got a rejection letter. Very misleading. I am getting the feeling that startups have to meet a quota of interviews for their investors
