Vanta Software Engineer Interview Experience — A Rough Technical Round Got the Next Day Cancelled

All of this had come up before.

Coding:
Implement a command line tool, uniq, with global uniqueness.
Follow-up: what if the memory can't hold the entire hash table?

SD:
Metrics for most viewed URLs / subscription conversion rate of their web app.

I didn't do well on the technical round, and the interview scheduled for the next day was cancelled outright.

Feedback from the recruiter:
Overall the team appreciated your strong technical capabilities with regards to bug-free code and requirements gathering. At this time the team has decided to prioritize candidates who had stronger, complete solutions and justifications for their technical decisions.
