"What would you use if you cannot use Terraform for a project?"
To which I initially answered, since it was a SENIOR position, with a warning about mixing Terraform and non-Terraform managed infra because it can lead to unforeseen issues, especially if there are less visible dependencies between the 2. I then mentioned anyway it could be done with Python + boto3, with AWS CLI + bash, with Pulumi, with CDK and then after some extra talk, also with Ansible.
They didn't want a long answer with lessons learned in real prod, they wanted a oneliner answer: Ansible. They told me then to be shorter in next answers and proceeded to ask like 30 questions in a row involving bash, Linux, Terraform and Kubernetes knowledge, to which I answered all correctly (and with the one-liner answer).
The result: discarded, because I chaotically answered to that first question. Although I was somehow offended because I don't like to be discarded, I think I dodged a bullet in this case.
