Akropolis interview questions

The whole process was quite unpleasant. The founder was directly interviewing me for the role via video call. She did not turn on her camera for the whole duration of the call and it was over in 10 minutes. She seemed very uninterested. She asked me to do cohort analysis on their token which I turned in within a week. Silence for 2 weeks till I followed up with them. A member of her team who didn't seem to have any idea of product reached out to me asking me to do more analysis by stating that the analysis did not have any insights. I suspected that they were trying to get free work out of me under the guise of an 'interview". I sent in a response on how I would go about doing the analysis for further insights, without mentioning any new insights. Did not hear back from the team after that. The team did not even have the courtesy to send a rejection email after such a long drawn out process.
