I'd like to clarify one thing - none of your communications with BaseCase were 'automated' on the BaseCase-side. Every email that was signed-off by a person was manually sent by someone on our team. For 'common' emails, we do use email templates, but a person actually decides to send the template, not a bot.
(Technical detail: the second software test uses an email bot to time the test, but this bot is not reporting your recruitment status in any way, it's just sending the test and receiving your solution. It identifies itself as a bot in communications.)
I have asked our recruitment manager to send an acknowledgement email after every test submission (they usually do, but in your case you're right that they didn't).
Regards,
Diarmuid
