I had 4 interviews and still had some outstanding questions pending the final interview. HR wanted me to chat with a director after hours (7pm) instead of scheduling time during working hours. I was also contacted via text instead of email, which I find strange and like to keep professional things to email. I sent my questions over email to be discussed on a later call or perhaps just answered over email to avoid scheduling conflicts and efficiency. I was called unprofessional and told I lacked interest in the position because I sent these over email.
