Emma interview questions

The process started with a first email requesting to perform a 12 minute cognitive assessment. I personally don't feel like this test is empathetic or fair to the candidate's full skills, but it's the one Emma decided to use to filter candidates. After doing it I was invited to a first 30 minutes interview with a recruiter. The recruiter was nice and enthusiastic, however the whole interview felt rushed, with nearly no time for my questions. One thing I felt very uncomfortable with was the fact that the recruiter asked me to give 3 ideas to improve customer retention in less than 5 minutes (I do not expect this from a non technical person, neither in a screening interview). After a week I got an email saying that the position I was applying for had been closed, since an internal solution had been found. I find it really questionable and deceitful to waste one's time, requesting for free ideas in a first interview and then ending up deciding to go with an internal resource. Emma, don't open vacancies if you're not committed to hire someone.
