Chicago Trading Company Senior Data Engineer interview questions

Got a call from 3rd party recruiter. Applied online and the CTC recruiter called for a phone interview. Got interview scheduled with director and account manager. After that got an assignment which must be finished in 2 days. Requested for python-based assignment. Got one in Python and another one in Java. Completed it on stipulated time and informed the recruiter. After that no response from the 3rd party or CTC recruiter on the feedback for a week. Later I got an automated email saying they are not proceeding with my profile. This was a disappointing response without giving feedback on what went wrong. At least a session where they review and whats the issue to reject me or an email explaining the details could have been sent for courtesy. Both coding assessment was of hard complexity as in FAANG interviews
