The Danger Zone: Top Reasons Candidates Fail
Based on our database of Lexroom interview outcomes, avoid these common traps:
- Using overly complex or inefficient fuzzy matching algorithms without justification.
- Focusing on the disagreement itself rather than the process of resolving it.
- Inefficiently storing all events and iterating through them for each query.
- Poorly defined request/response payloads, lacking necessary fields.
