Intercom Systems Engineer interview questions

Applied online and received an email from a recruiter to go over recruiter screen via Skype and received an assignment email to complete within few days including details to follow stereotype guidelines while submitting the code. They were expecting a candidate to spend several hours during the current job to come up with a codebase with test cases. Personally, I do not like such stereotype thinking rather go with the candidate on a coding round with an interviewer who can observe candidates thought process and idea of implementation. Submitted code with production standards and received email stating: "You provided a thoughtful answer regarding the tool you had written to keep a data pipeline working well. We liked that it worked well and was well received - great job Unfortunately, however, we're not going to proceed with your application this time, as we feel other candidates have come closer to what we're looking for, particularly in the area of production ready code and automated tests. We've decided to focus on more senior candidates with substantial programming experience."
