Smartsheet Customer Service interview questions

Applied online. Was contacted the same day to setup a phone interview/screening. Arranged interview/screening call for the next day. Typical screening questions about my background and experience. Recruiter asked if I had used the software. I acknowledged I had not - it had only been 1 day since discovered the company and I applied. Recruiter asked that before they put my application in front of the hiring manager if I would take some time to install the software and write up thoughts and feedback about the software that they could include with the submission to the hiring manager. I agreed and spent a few hours the next day working with, reviewing, and writing up my experience and thoughts. Submitted details and did not receive acknowledgement from the recruiter. Waited a couple of days and then sent a follow up email, with details attached, asking if they received the information and if there was anything further they needed - no response. Sent a third follow up message - no response. Very unprofessional.
