Standard recruiter screen, a quick Coderpad quiz to assess basic React, JavaScript, HTML, and CSS fundamentals. The next round cranks the difficulty from a 3 to 10. On a 45 minute clock, you need to add table drag/release functionality to highlight cells (similar to Excel or Sheets). If you aren’t strong at algorithms, you’ll likely fail this. My experience was miserable, their office was extremely loud and I struggled to focus and my interviewer was somewhat helpful in design but this just isn’t a reasonable assessment on a 45 min interview as someone who has cleared several staff interview cycles at later stage companies. Personally, I’ll never consider Flatfile again.
