Acumen Companies interview questions

Started with assessment on vocabulary and quick thinking, was contacted for an interview following the assessment. Interview was very off-putting and lasted less than 10 minutes. Was told I would receive a case study with next steps. Followed up three times, and never heard back. Upon third email, the contact I reached out to had a disconnected email. Very poor communication and still have not heard anything.

After applying they quickly reached out with an hour long online assessment to complete. This included vocabulary and logic style questions. Following completion of this they were supposed to contact me again. They did not and did not respond to any follow up emails.
