RepairPal interview questions

Brief phone interview after online resume submission then in person interview with manager and senior success managers. They asked me how I would handle a difficult customer who called in. what my most challenging job experience has been and how I handled it. also asked if i was interested in company volunteer events

Seemed pretty typical at first, but as the process progressed it became SHADY as hell. At first the hiring manager was pleasant and appeared to be genuinely interested and invested in hopefully hiring me to join the team, but that's when the 'funny' stuff started. I know it's quite common to ask for samples of work or to prepare a presentation or the like but it was different here, bordering on what felt like being taken advantage of. In my naivety I thought it was part of the process to 'prove myself' but in retrospect I now know it was too much and it wasn't right. Like the other interview review, many hours were put in to produce thoughtful solutions and features as well as during the onsite 'working session' with the team; a feature proposed seemed to 'magically' appear onsite later. I do hope I wasn't jumping through hoops for nothing so that they could get 'free work' from applicants, but it sure felt like it. The kicker was that after all this time and effort -- phone calls, homework, onsite work session/interviews -- in which I earnestly thought might result in offer, and after I was told I would hear back the next day with a decision, I was then totally 'ghosted.' Follow up emails inquiring about the status of the open role/my decision were summarily left unanswered/never replied back to ever. Very, very unprofessional and a total waste of time.
