The process began with a recruiter call explaining the requirements and steps involved.

The first round was an outsourced phone screen. The instructions mentioned focusing on code completeness, not performance optimization. I believe I performed reasonably well within the given timeframe and for the question asked.

After 4-5 days, the recruiter contacted me, stating they would not be proceeding. No feedback was provided regarding what went wrong or areas for improvement. I suspect this may have been a training exercise for the recruiters or a vendor validation process. Please do not waste candidates' time if feedback cannot be provided.
