Intercom Customer Support Specialist interview questions

I applied for this role via LinkedIn in April. A few days later, I was contacted by Intercom asking me to complete a take-home assessment, which I did, and after sending it back I was informed by Intercom that they will bein touch soon with feedback. I never heard from them again. About a month later I decided to follow up on this as I strongly believe in companies providing feedback to unsuccessful candidates, considering one takes time out of their day/work to take part in the recruitment process. I was hoping that if I eventually receive feedback, I could at least learn something from the experience. I did not receive a response. Now, over a month later, Intercom have sent me an email to say allegedly they have been in touch with me regarding progressing with my application, but I never got back to them, so they had to cancel the application. This is completely and utterly untrue, as even after following up with them it took them a month to respond. It is shocking that for a company whose purpose is communication, the recruiting team are so disappointingly bad at communicating and are so unprofessional. If you are looking for talented and capable people to join your company, please put in the bare minimum into your recruitment process.

I received an e-mail to confirm that I would go to the next stages. They asked me to answer some questions. After preparing very well and send it to them, they replied after a few days that we wouldn't progress. They didn't gave a proper feedback. I felt that it was a waste of time.
